About cameras, formats and smart tips…
I wondered why and Mr. Johnson explained that the photographed image file itself can not be changed, but the developing technology of Raw files will improve in the future, so it will be possible to generate higher quality output from the very same files.
Boy, was he right …
So, Why Raw?
Raw format keeps all the information that was captured by the sensor, without intervention and without processing. The color depth of the captured data, is 12, 14 or 16 bit (depending on camera model), as opposed to a JPEG image file which is fully processed by the camera, has only 8 bit color depth and uses lossy compression that significantly reduces image details.
The so called “Disadvantage” of Camera Raw format is that you must “develop” the raw file and save another image, in JPEG or TIFF format that will allow you to use it in common software. In fact, this is the biggest advantage of Camera Raw format… Raw develop software presented a significant progress in recent years, so you can always go back to old files and produce enhanced images that could not have been produced in the past.
This version had no support for camera profiles, no support for lens profiles. It didn’t even know how to handle Highlights and Shadows separately…
Notice what happened to that file when I developed it with a newer version of Photoshop, which includes support for cameras and lenses profiles and equipped with advanced brightness, contrast and color control:
It’s quite amazing to see that the camera’s dynamic range is so wide. The old software, simply could not extract all the details from the file! The new version extracted much more details in various brightness areas, the colors are much deeper and image quality in general, is dramatically improved.
Notice the loss of information underneath the bus, its yellow color, the red color of the sign behind its right side and the color of the road.
It’s easy to notice the improved contrast, the enhanced colors and the lens distortion correction. This is the result of the implementation of much more advanced technology, into programs almost every photographer is familier with, Lightroom and Photoshop.
The obvious conclusion for me, is the title of this post – Wise People Shoot Raw,
because the wise avoids situations the smart has to find ways to overcome 🙂
Wish you a successful and productive year, a lot of good photos and don’t forget think about the future of your images …
