arablizzard2413 Posted September 23, 2005 Posted September 23, 2005 I have several images that are different shades but they were all created from the same grayscale "original", now my question is this: how can I use these images to get that original grayscale image and save the hue/colorize settings for later use (I have a huge set of these and I want to be able to run through them quickly).Here is an example of the pictures I'll be using (all put on the same image),I'd prefer to use Photoshop CS 2.
FthrJACK Posted September 29, 2005 Posted September 29, 2005 just desaturate the image and save a psd of it.. that is what you mean right?
arablizzard2413 Posted December 24, 2005 Author Posted December 24, 2005 No that's not what I mean, if you desaturate them they are different; they were all made using the original source but if you desaturate them you get a greyscale version of that particular shade (the darkest will still be darkest, the lightest will still be lightest, etc). I'm trying to rebuild the original image that those files were made from (hard to explain I guess, but if you look at those 4 pictures, they look like they've been colorized, but they are the same picture).
liquidplasmaflow Posted December 24, 2005 Posted December 24, 2005 I don't think you can get the exact original image, but you could average the 4 images and get something in the middle.
galvanocentric Posted December 29, 2005 Posted December 29, 2005 I don't think you can get the exact original image, but you could average the 4 images and get something in the middle.Yes, unless you've got A) a photographic memory or B) pixel-perfect printouts of the original backups, restoring the original exactly will be impossible. Pixels have been altered, you'll just have to do an average best-guess.
arablizzard2413 Posted January 6, 2006 Author Posted January 6, 2006 ok, so how would I get an average of the 4 images? (in Photoshop using all of them)
jcarle Posted January 7, 2006 Posted January 7, 2006 Cut each quarter and paste them one on top of each other using a seperate layer for each. Desaturate each layer, set opacity 25% for each, then flatten image.
liquidplasmaflow Posted January 7, 2006 Posted January 7, 2006 I think the bottom layer needs to be set to full (100%) opacity for that to work.
jcarle Posted January 7, 2006 Posted January 7, 2006 I think the bottom layer needs to be set to full (100%) opacity for that to work.Nope.When you flatten image, all four layers are combined and any transparency is filled.
arablizzard2413 Posted January 7, 2006 Author Posted January 7, 2006 That flattens everything onto a white background (detail is lost), but thanks, I think I have it now.
