Android App News - WhatsApp adds a New Voice Message Option

 



WhatsApp adds a New Voice Message Option. Today WhatsApp adds a new voice message option to its popular messenger app. Instead of writing or recording a message and then adding it to a conversation, the user can just push the button, record his message and when the button is released, the message is sent automatically to the recipient contact.
We tried it and it works, naturally. We had to remember to wait a second after pushing the button before starting to talk, otherwise the start of the message will be cut. In addition, on several cases it took several minutes for the message to reach its contact while other times it arrived almost immediately.

We might add that this upgrade will appear automatically, though it seems different users get it on different times.
 





How to Photograph A Wedding Dress – Tips for Capturing Detail in Wedding Dress

Is detail in a dress (generally pure white) that important? It is; especially so in the case of a wedding gown. Many days or even months are spent choosing / designing a wedding dress and its worth much to the bride both emotionally and monetarily. Most brides take pride in their selection of wedding dress and want to look their best in their wedding album.

Also creating a wedding dress is a collective work of several artists (costume designers); an arduous task that takes several days; if these hard made details in a gown is to be captured perfectly in your shots, you need to be aware of certain properties of white dress and also master some techniques to deal with them. In this article we will discuss one such technique that will make sure you successfully capture all detail in your brides dress every time.

When shooting bridal gowns, photographers are faced with two major challenges:

1. To meter and expose the shot properly
2. To capture detail in the dress in the photographs

Shooting in Auto Modes - Use Exposure Compensation

A vast majority of bridal gowns are white and this brings with it the perennial problem of photographing white objects. The camera’s meter will think of the white gown as a grey subject in very bright lighting and it will set the exposure to capture the subject as grey. Shooting in any of the auto / semi auto modes need sufficient compensation to get proper exposure. It depends on the metering mode you have set but usually an exposure compensation of +1 should do the trick. Those who shoot in fully manual mode need not worry about setting exposure compensation.

One trick to minimize exposure issues is to use spot metering mode and meter from your subjects face.

Check Histogram for Highlight Clipping

Regularly check your histogram to make sure you are not clipping your highlights, in this case it will be the white wedding dress that will get blown out taking all detail in the dress along with it. Remember details in the wedding dress are important.

Shoot in RAW Format


Shooting in RAW format helps you to capture the scene with more dynamic range. It also gives flexibility in post- production to change white balance settings.

Tips for Capturing Details in the Wedding Dress

Please see our earlier article on’ How to Photograph Texture’; the very same principles apply here. The trick is in the way you position bride in relation to your lights; the idea is to let the light rake across the surface so that it accentuates the shadows and brings out detail in the fabric.

The best way is positioning the bride so that her shoulder closest to the camera is angled towards the light.  Be it a soft-box or a large window. Angling the shoulder towards the light is important because if the shoulder closest to the light is not in front, light will hit the wedding dress straight on and will result in flat lighting that captures little or no shadow and detail.

So first and foremost thing for better capture details in wedding dress, the shoulder closest to the camera should be aiming toward the light.

In wedding photography oversights are not pardoned. A photographer gets to shoot a wedding photo based on his/her reputation; this makes him under perpetual stress to keep his reputation intact in this field. So as professionals we need to do that extra bit to make sure what’s important for our clients are all present in our pictures just the way it should be.  Climb any mountain or ford any river to keep up your reputation. 

Android App Review - Booking.com - 330,000+ hotels


Android App Review - Booking.com - 330,000+ hotels

 



Booking.com - 330,000+ hotels app. The booking and reservation app from what is probably the biggest booking site on the world with arguably the largest hotel, hostel, apartment and even more kinds of accommodation, this app has almost everything that one needs to make a reservation quickly, even while on the move, and manage it including check in and notification, everything done simply with the Booking.com app.



The app itself aims for simplicity, with as few buttons as possible, just the searching button, filtering and sorting and then going over the hotels themselves, seeing their reviews, photos and scores. Everything you need to make an educated accommodation choice. 

The booking.com account allows you to sync and manage your reservations on the Booking.com app, on a desktop and on the website itself, complete with checkin and notifications.

Naturally, we did have some small issues with some things. It seems Hotels.com has more last minute deals and promotions, though at this time we have yet to perform a comparison between the major booking apps. We would have liked to be able to review the hotel we're staying in right from the app. 

After the last update one of our testers could not open the app and he had to uninstall it and then download it again from Google Play. Another made a reservation that turned to not exist - to this day we're not sure if the problem was in the hotel, Booking.com app or the tester himself made a mistake.






  • Score: A 5 out of 5, because of all of our testers found it easy to use, liked the map and it delivered exactly what it offered.
  • Description: A hotel booking and reservation app that builds on Booking.com extensive hotel network to provide the users a huge amount of hotels and other kinds of accommodations to select from. Including notifications, searching and filtering, map orientation and reservation managing, this is one of the best booking apps on Google Play today.
  • Good Points: Our testers liked the map, seeing all the hotels relative to their location. We also liked the simple interface, the amount of hotels available and the reservation notifications, which were very useful. Of course, seeing so many pics of the hotels to select was also great.
  • Bad Points: We didn't like the fact you cannot review a hotel from the app. Since you book it from the app, and you carry your smartphone with you all the time, why not let the user write a review right there on the spot? And as is the case with so many apps, we did encounter some problems after the last update.
  • Experience: Again, disregarding the update, the app worked almost flawlessly on almost every smartphone. Our testers found it easy to use and liked the ability to flick through images of the hotel they were interested in, including pics of the rooms. All in all, all agreed this is a superb booking app.
  • Longevity: People are keeping this app on their smartphones, no question about it, even if some have other app as well, such as TripAdvisor and Hotels.com
  • Google Play Link - Booking.com - 330,000+ hotels

How to Photograph Abandoned Places and Buildings – Urban Exploration

Ruined structures pertaining to the Roman Empire, Greece, Mexico, Italy etc. that bear markings left by several centuries, locations in the Middle East where Jesus walked and preached, numerous Indian palaces and temples, Machu Picchu of South America, Buddhist temples from Gautama Buddha spread throughout Asia; the list is endless!  When history remains frozen in these ruined structures; they have a thousand stories to tell; we photographers are duty bound to present their stories before the world. 

Temples, historical sites, old architectural marvels which stood as the wonders of the beholder for centuries lie in shambles; they are mere scattered stones that have nothing but a glorious past. One need not wander to Egypt or Rome to find them; they may be in his on town; unwept and unsung. No doubt that they are decayed (beautifully decayed may be more apt). Paying a visit, studying their history and bringing out images exposing their uniqueness are no mean things.    

Urban Exploration

It is a general feeling that old and dilapidated structures and places contain nothing of any value; and people view with suspicion to those who visit such places; they are unaware of what actually these structures are and what they hide in them. Photographers can do a great service to history by unraveling those treasures hidden in them to the outside world. Such a visit can be called ‘urban exploration’; it can be made a hobby that can both enrich the mind and create value to your works.

It would be better to consider these matters before taking ‘Urban Exploration’ as a serious thing.

1. Abandoned Places and Buildings Are Dangerous.

Abandoned places, especially buildings are generally very dangerous, years of neglect and the play of nature’s elements would have made everything in such a location in varying degree of decay. Much care is required to work safely. Some of the hazards may be noted below;

Concrete Decay


With passage of time, concrete decays (called ‘concrete cancer’); the steel used in them rusts and this combination makes the entire structure highly unstable; using of parapet or staircases must be done at one’s own risk. A slight fault can cause damage either to the structure or to the person.

Holes


Abandoned structures like elevator shaft, service vents, wooden planks etc. can cause a fall in to a bottomless pit; without anybody nearby for a rescue.

Slippage and Allergies

Most abandoned buildings are covered with a thick layer of dust, moss, fungus and other pollutants, these can cause slippery surfaces and exposure to toxic substances like asbestos fibers could cause serious health hazards.

Wild Animals and People


Abandoned places and buildings can be favorite hide outs for wild animals, pack of stray dogs, poisonous snakes etc. These places or buildings are generally frequented by criminals, druggies, etc. most of them fiercely territorial and aggressive; take care against mugging or theft of valuable equipment. 

2. Entering Abandoned Buildings is Illegal.

The mere act of entering an abandoned building is illegal and if caught will have trouble of clearing the charges of trespassing or violation of the law just for being there. Such a thing if it happens in a foreign nation may be taken for espionage; no one will be there for a bail. So before setting out you should be prepared with all credentials to convince the officers and seek an early escape!

Urban exploration is a dangerous hobby that can either cause physical injuries or get accused with some serious charges by a court of law. So to summarize it could be done with collaboration from those who have necessary contacts to get bail out!

After hearing all these; still ready for a rendezvous? Ok being a photographer; it is hard to resist a temptation. There is a very special kind of beauty in long abandoned and ruined buildings and that combined with the thrill of doing something risky, the adrenalin flow when you take risks never knowing what’s going to happen next, and prospects of getting some really amazing photographs all makes it irresistible.

Certain Must Have Accessories for Urban Exploration

Words of caution before we begin, never vandalize, steal, or damage anything; Leave everything just as you found it. Leave only foot prints and take back only photographs and memories.

A Torch or Flashlight


Never ever enter any abandoned building without a torch or a flashlight, they are dangerous places, they are almost always dimly lit and most definitely without electricity. A flashlight can become a weapon to scare away ‘troubles’ and can function as an aid for some ‘light painting’, or to reveal details in shadows to make your photographs all the more interesting.

Drinking Water


Urban explorations almost always takes more time and effort than you initially thought it will, be prepared for lots of walking, stair climbing and navigating some tight corners etc. take some potable water to keep you well hydrated.

Camera


Urban exploration is a trip to an unchartered territory; your ‘return trip’ can be ‘quite unceremonious’; It is advisable not to carry very expensive cameras and accessories, only carry a camera you are prepared to lose, break or get stolen.

Money


Do not carry excessive amounts of money, some spare cash could help you get permissions, or get out of trouble if get caught, but carrying more cash can be a passport to trouble.

Urbex Tips - Exploring of Abandoned Places and Buildings

Try to find out the authority that is in charge of the building and ask permission, often a nearby resident would be acting caretaker and will be more than willing to allow you inside or even escort you there.

Before actually entering the building, Scout the location, do some backgrounds research both online and offline and try to find out as much as possible so as to keep you away from trouble.

Never ever go alone to an abandoned location or building, try to coax someone to come along, try teaming up with photographers of similar interests, if you really need to go alone, make sure to inform someone who really cares about you about the location you plan to visit and when they could expect you to return.

Tips for Photographing Abandoned Places and Buildings


Find an abandoned building


In order to photograph it you should find one first, It doesn't matter how drab or plain it looks. It could be a long abandoned structure infested with weeds, climbers and all or a recently-abandoned one of some importance.

Pay Attention to Surroundings


Don't forget the area around the house. Grass, trees, scattered things like toys or broken furniture parts vessels, shoes etc. could all help you narrate a story with your photograph.

Shoot Wide

A wide angle lens can really add to the sense of emptiness and foreboding in these buildings and it gives viewers a feeling of being very close to the objects.  

Emphasize the Mood

Explore the scene from different angles and try to use perspective to emphasize the natural character of the building. Consider shooting from low down or tilting the frame to emphasize the mood of the photograph.

Capture Abandonedness

Try to find elements that scream “abandoned” and use it in context to bring focus to the emptiness or abandoned-ness.

Attention to Detail


Pay attention to details, the little things that often go unnoticed if used properly could add life to an otherwise dull photograph.

Composition

Plan your composition carefully, the picture needs to tell a story, a story of neglect, one of decay, one of past glory, about people who once lived there etc. think ahead and find interesting subjects. Innovative shooting angles and unique compositions can effectively narrate your story to the viewer.

Preservation

Take up urban exploration as a hobby with some interest in the history of the places you explore.  Photographing abandoned buildings is a way of chronicling our past in pictures.

Mental Awareness

Just like in wildlife photography, urban exploration also calls for an awareness of your surroundings at all times, not only is it crucial for capturing amazing photographs but is also important due to the hazards posed by abandoned buildings.

Old is gold;

If a once sunken ship -seen by nobody- can make billions; you too can make a fortune out of dilapidated structures; in a la Titanic way. It needs some hard work; let the people of the locality talk freely; enquire who lived there; how they lived and died; details of their siblings etc. Then meet all possible siblings collect all the photographs available (of people as well as the building in its prime time).  Along with all these add your own version in photographs; some romance if any! If your story is a hit; a real jackpot; old may turn to gold! Have a fruitful rendezvous.

Focus Stacking an Introduction



Focus Stacked from Three Exposures
Focus Stacked from Three Exposures


Focus stacking is a technique used in photography to extend the depth of field in a photograph beyond what the lens’s highest f/stop is capable of rendering.

Normally to increase the depth of field photographers stop down the lens (use narrower apertures) but beyond a certain limit narrowing down the aperture will cause diffraction which significantly degrades the quality of the photograph. Also choosing higher f stops increases the exposure time.

Application of Focus stacking


Focus stacking is not suitable for every occasion that requires more depth of field. Typically focus stacking is commonly used in the following genres of photography.

Macro photography:


Lack of depth of field is the most severe issue faced by macro photographers. The greater the magnification the shallower the depth of field; often times the lens’s minimum aperture (f/22, f/32 etc depending upon the lens) fail to achieve sufficient depth and stacking multiple images remains the only option.

Landscape photography: 


Landscape photographers often desire everything in their frame (from a few inches in front of the camera to infinity) to be in sharp focus, combining two of more photos to obtain the required depth of field helps avoid softness at the focal plane caused by diffraction.

Low-light photography: 


Stacking multiple photographs help photographers avoid using prohibitively long exposure times, to freeze motion in parts of the frame while capturing expansive depth of field in others without using flash etc.

Limitations of Focus Stacking


Even though focus stacking is a very powerful technique and at times is the only way to achieve the required depth of field; it definitely has certain disadvantages:

It requires elaborate set up, depending upon the subject being photographed, and the intended final use of the picture, photographers need to use accessories like, sturdy tripods, focusing rails, remote shutter release etc to precisely capture the many shots required to stack. Setting up all this requires a lot of time and effort.

To capture the various exposures necessary for the final stack the subject need to be motionless.

Focus stacking, especially those shots that require a large number of photographs need specialist equipment like focusing rails, it also requires specialized image editing software like Adobe Photoshop or Combine ZM to combine all the photographs into one.

Capturing, storing and processing many photographs instead of just one with sufficient depth of field require more storage space and computing power.

Alternatives to Focus Stacking


There is another technique called Depth of Field Stacking in which different images are taken at varying F stops and later combined to extend the available depth of field. Although this technique is easier than focus stacking, it cannot increase the depth of field as much as focus stacking can.

Alternatively the tilt movements of a Tilt/Shift lens could be used to capture various images by re-positioning the depth of field to different areas.

Focus Stacking Technique


Focus stacking requires several photographs taken at different focusing distances to be stacked into a single photograph which has the combined depth of field of all the individual shots. Focus stacking is a three stage process; the first is capturing the individual photos required for the stack. Second stage involves aligning all the individual photographs properly and the third stage is the actual merging and blending. We will look into each of these stages in detail.

1. Capturing The Photos


The most important decision a photographer need to take is the number of photos required for a particular subject. The key is to ensure that the depth of field of each subsequent photo overlaps with the depth of field from the previous photo. This will ensure that there is no softness in the final composite. More closely spaced focusing distances often produce more consistent and natural looking sharpness, but this can take a lot longer to capture and requires more storage space. On the other hand if the photographs captured have too widely spaced depth of field it will result in a wave like depth of field effect which could ruin the final composite.

Optimal F-Stop


Using higher f stops significantly reduces the number of photos required for the stack, but this can also decrease the sharpness of the final image. The trick is to find out the narrowest aperture that could be used (in the lens that you intend to use ) without causing diffraction. Generally for most DSLR lenses it will be somewhere between f/8-f/16.

Shooting Technique – Step By Step


  1. Set up your camera on a stable tripod.
  2. Connect remote shutter release if you have one.
  3. Compose your frame.
  4. Shift your lens to manual focus.
  5. It is recommended to shoot in fully manual mode and use RAW as your file format.
  6. Set your lens to the optimal f stop.
  7. You could either start from the portion of the subject which is closest to you or from the part of the subject that is farthest from you.
  8. In macro photography you have the option of either using the focusing ring to change focus or physically moving the camera back and forth. Both methods have advantages and disadvantages. Experiment and find the one which better suits your style.
  9. Live view mode in your camera is a great tool which helps focus stacking much easier. It is even better if you could shoot tethered to a laptop as the bigger screen allows you to precisely align the focus.
  10. Take as many photographs as required, make sure you overlap each frames depth of field by at least 25%. This is easier than you might think especially when shooting in live view or tethered.
  11. Get through your series as fast as possible as any change in subject position / lighting conditions could create many complications while post processing.

2. Aligning the Photos


Effective focal length of a lens changes with focusing distance and as a result angle of view also changes, this makes the individual photos we took to be slightly misaligned. The effect is more like zooming in or out, when you focus nearer it appears as if you have zoomed in and when you focus farther it appears you have zoomed out. 

In Photoshop, click File > Automate > Photomerge.

Select the images you wish to stack together, make sure Blend images Together box is clicked and you could combine aligning and merging together.

Alternatively you can

Paste all your photographs as layers on a single document.

Click  Edit > Auto-Align Layers

3. Merging and Blending the Photos

With simple subjects which have well defined layers merging and lending is a pretty straight forward process just the same as aligning layers.

In photoshop click Edit > Auto-Blend-Layers

Select blend method as stacked images, make sure create seamless tones and colors are checked.

But in situations that have irregular layers you will not get satisfactory results from the auto blend method and will have to manually edit which photo contributes where by using the layer masks.

Zoom in and inspect your final result at high resolution for imperfections and make corrections using the layer masks if required. Once you are satisfied with the results 

Click Layer > Flatten Image and you are done.
