How To Crop In Camera Raw By Image Percentage
You've probably seen (or heard) a bit of talk about RAW images and Android lately. Some of united states of america are pretty excited about what this brings to our smartphones, and the very cool stuff we tin can do with RAW images transferred to our computers. And some of us are a little dislocated about what a RAW image is, and why all these Android photographic camera nerds are excited almost it.
Simply put, having a camera on your Android that takes RAW images means you have a better set of image data to apply when editing the motion picture than you would with a standard jpeg image. While the small sensor and stock-still focal length on a smartphone means it won't measure out upwardly to a "real" camera, you can now capture shots with your Android that simply weren't possible before. HDR can simply do so much ...
Let's get our easily dirty and wait at what a RAW image is, and what you tin can practice with one once yous've captured it.
READ At present: RAW images and Android
What exactly is a RAW image?
If y'all grab an Android fresh out of the box and have a motion picture with the photographic camera, you'll probably go a rather nice looking moving picture placed into your gallery. The image y'all get was congenital from the data the sensor collected from all the tiny points of different colored light (the pixels) and optimised for things similar balanced whites, sharp edges, and racket reduction (among other things) so given a last pass optimization and so it looks cracking on your screen. When this is done, the extra image data is discarded. The final consequence is a jpeg epitome that has a much smaller file size, and is built using special software to look equally adept as an algorithm thinks it can look. If you accept a mod Android, you're probably going to be pleased with the effect nearly of the time.
When you lot accept an Android that is capable of shooting in RAW + jpg, yous get the same output as above, plus a file that contains a minimally processed version of all the image information collected by the sensor. The sensor collects information from areas that are very night, or very light, or that appear to exist the wrong colour to our optics and more, merely usually discards a good portion of this after jpeg optimization. In a RAW image, this data is kept so that special software can manipulate information technology.
Y'all probably don't need to utilise the RAW format for most of the pictures yous take with your Android. On a phone like the LG G4, the jpeg output is well optimized and is likely equally skilful as your consequence would exist if y'all used all the image information and built your ain jpeg from it with an epitome editor. Sometimes, though, you tin can utilize the RAW data to fix an image that the automatic algorithms tin can't seem to get right. And some of u.s. just like to toy with things — RAW files are perfect for that.
What RAW file format does Android use, and why does it matter?
Android (as of Lollipop 5.0) has a method where the camera can capture RAW images in the DNG format. DNG (Digital Negative) is an open lossless RAW epitome format written by Adobe in 2004. It'due south based on the TIFF format, and the files comprise the prototype data, at least one .jpg preview, and metadata that allows programs to read and edit the file. This is why they are such big files — there is a lot of information in there.
For the folks writing Android software and building Android devices, having an open standards-based file format is pretty important. They can easily and freely distribute the software as well as update for newer versions besides as ensure backwards-compatibility. And there are less royalties to pay — every penny counts.
To users similar yous and me, this only matters when finding software that tin view or edit the files. DNG is a widely adopted format, and you'll find it'due south well supported in many image editors on Windows, Mac and Linux (and even lesser-known Unix variants). Chances are you already take software on your computer that can view DNG files and brand small edits. We'll look at dedicated programs to edit DNG files in the adjacent department, simply know that RAW for Android uses a well-supported and popular format for anyone who wants to dive in and practise some serious editing.
We too take to call back than while RAW support is actually absurd and allows for some amazing edits to the photos we take with our Androids, it does nothing to increase the limitations of a small-scale fixed focal length camera. We're not going to be able to capture equally much data as a larger sensor camera, and your smartphone isn't going to supplant a DSLR any time soon. Become into things with the right expectations so you're not disappointed.
How practice I edit my RAW files?
For starters, you lot'll need to sympathize that a computer is necessary for the best results here. I'grand sure someone, somewhere, is decorated edifice a really adept DNG editor for Android. Simply to make the nearly out of your RAW images you need a big screen and fairly complicated software. So plug your phone in (or employ another method to transfer the .DNG files from your phone to your computer) and salve a copy on your figurer.
There are enough of options for RAW file editing on the figurer. Windows and Mac users can apply Photoshop or Lightroom (as well every bit less-expensive or even free alternatives like GIMP or Photoshop Limited) and most Linux distributions will take a package for DarkTable, ImageMagick or digiKam also as GIMP. I do most of my RAW image editing in Lightroom, but the alternatives work well and there is no one best choice.
Once you accept the file and the software to edit things, you tin begin to adjust things. You should have complete command over exposure, white balance, sharpening and the like, and you can make non-destructive adjustments to the paradigm data. It might take some practice to brand the images wait as good or better than the photographic camera's jpeg output, but it tin also be pretty darn fun.
What all this allows you to practise is shoot your pictures to get good focus and framing, so conform the exposure and do any sharpening or noise reduction by hand afterwards. You tin take some spectacular photos this way if you lot want to accept the time to play with things. The prototype you see above was shot in transmission way with the shutter open up for .5 seconds to make the water await the fashion it does. I and then transferred the RAW file into Lightroom and made the exposure a flake "darker" (a deadening shutter makes everything as well vivid) to get the finished picture. Something like this can't be washed with automatic modes or jpeg images.
If yous don't experience like taking the time to play with things, always remember that your camera probably takes great photos with everything on automated, too. Non every picture needs to be shot in RAW and edited, and not everyone wants to go through all this to go a good picture.
Does my Android take RAW photos?
Maybe. A pre-requisite is Lollipop, but non every Lollipop phone uses the camera2 API that allows RAW images to be taken, and not every camera app uses them on phones that exercise support information technology.
- The LG G4 takes RAW photos with the stock camera app
- The Nexus six takes RAW photos with a 3rd political party camera app
- The Samsung Galaxy S6 is expected to become RAW camera support with a coming update
- The HTC One M9 takes RAW photos with the stock camera app
Other phones may also support RAW capture, and updates may bring support to phones like the Notation 4 or the Moto 10 which do not currently support the whole of the camera2 API. The best bet if you take questions about RAW back up is to check the forums. They know everything in there. Utilize them.
If you're looking for an app to take RAW photos, there are plenty. The popular ones are Transmission Camera (opens in new tab), Camera FV-five (opens in new tab) and 50 Camera. I've used all three on the Nexus 6 with skillful results, but once again hit those forums for more recommendations.
