After playing with the possibilities of the camera, certainly very interesting, I have resorted to manual application to locate and get my photos in RAW format (if not found). I have done several tests, will let only 1 of them (the results were the same). On one hand I captured the photo with the standard application of the iPhone camera, and then the how to jailbreak iphone 4 same frame (okay, I've moved a little, but is similar) with app 645 Pro and getting the TIFF (BTW, I have had to look at the manual on how to copy the iPhone to the computer TiFF) again. If you want to download the original files, here I leave you [zip 8.4 Mb].
I have spent the files to Lightroom 4 (btw! Next May 19, 2012 did a course on Lightroom). In this first picture you can see the original JPG without any adjustment: Here the TIFF without any adjustment: Then I corrected the most both Shadows and highlights, with the intention of seeing how the image could be recovered and behaved as both files. First I leave a JPG extension.
Well, you have seen the pictures taken. You find you any difference between JPG and TIFF? Actually I see exactly the same.Comparing the JPG files that makes the application itself 645 Pro with TIFF, if we're going to find many differences, but that JPG is not the "native" but that comes already applied for a few adjustments (grain, saturation, contrast) that performs the APP itself.
