The answer is obvious, if you arelooking for ultimate quality your image must not have any compression, by allmeans save a copy in JPEG but working quality must (in my oppinion) be the highest quality you can achieve, use Raw then convert to Tiff, store after producing a working copy Jpeg, uses a lot of space but there is no substitute for quality.


ImageVerifier does what you want. ImageVerifier (IV for short) traverses a hierarchy of folders looking for image files to verify. It can verify TIFFs, JPEGs. PSDs, DNGs, and non-DNG raws (e.g., NEF, CR2). IV is designed to process large numbers of images. Folder hierarchies with 100,000 images or more should be no problem. In one test run, IV ran for 14 ...


If I'm not mistaken RAW is unprocessed. Therefore any balancing, sharpening, or noise reduction is not applied to it unlike a JPEG. You'll have to adjust the white balance in post production. Most editing programs will have it listed under white balance, cast, or temperature.


Since you only have a black and white JPG there is no "color" information there. There is only shades of gray, "color" is lost. There is no 100% automated process to do this for you, you ll have to use a software to perform something like this: To perform digital colorization, a digitized copy of the best monochrome film print available is needed. ...


If this image were RAW, the color might still be there. But since it is JPEG, I'm afraid not. The fact that the image is in RGB format does not help, because I'd you look, you will find that in fact for each pixel, each of these values is set to the same thing: (0,0,0), (37,37,37), (221,221,221), or whatever. That is, they're all gray levels, just ...


Unfortunately, a JPEG is a one-way, destructive process. It may be RGB, but it no longer contains the colors originally present, only those written in the B&W conversion process. If you had the RAW (.CR2) file, however, you could recover the colors. Think of the RAW file as a master, and JPEGs are created from that.


There is one piece of software that I know of that can handle it: BetterJPEG. I have downloaded the latest trial, and, as it says on its web page can do lossless full-image color and brightness correction. The tools are crude compared to what is available in Photoshop, just a couple color sliders (red/cyan and blue/yellow) and a brightness slider. And ...


When I edit JPEGs, I don't want to use Lightroom's Export, because it always generates a new JPEG, and the additional compression may lead to a quality loss. Preventing quality loss due to re-compression is exactly the reason why you want to create new .jpeg files. LR always creates the exported images from the raw files and applies all changes. LR ...
