The color swap accident...
-
OK, so my parents-in-law have been to Corsica (fourth largest island in the Mediterranean Sea, according to wikipedia - lovely place according to my parents in law) for a 5 day hiking holiday. They went with some of their friends, who took a lot of photos with a Canon Digital Ixus 70 (aka Canon Powershot SD1000 outside europe). Unfortunately, the camera was in Color swap mode, which (according to http://www.photographyblog.com/reviews_canon_digital_ixus_70.php[^]) is this: "...whilst Color Swap lets you select a colour in the image and change it for another completely different one. " Whatever the setting is good for, it has turned all the pictures from their holiday into useless cr** and we need some help. I figure that given the description and given my imagination, the process of reversing a color swap is re-arranging the values of the rgb channels in the image somehow. I've searched CP (and found a nice GDI+ article from Christian, but it didn't help me enough), tried google, asked the graphics designer I work with - but I'm lost. It has to be possible, but how? If anybody has a good idea, a macro or instructions for adobe creative suite 2 or 3 or some code that can do something like this, we would greatly appreciate a helping hand :) If it can help in any way, I've put a sample picture here: corsicasample.jpg[^] - my mother in law is wearing a t-shirt that has the same color as the green in this smiley: :~ it isn't pink. Neither is her hair :) Comments, suggestions, code (is it ok to reply with code to a non-programming-question?) - everything is welcome. Thanks in advance for any help! /Jan

Problem is, if they just swapped red, green and blue channels around, fixing it is really easy. Just take one of my image processing articles as a template, and for each pixel, swap the values around. The values are stored b/g/r inside a windows bitmap, not r/g/b. If they have mapped to completely different colors, then you're going to have to work out the mapping and things become more complex. You need to work out the rules used to change colors, and write code to reverse them.

its possible. It would take some curve editing but you would loos overall image quality. :(

If it's just done mapping of one color to another, why would you lose image quality ? That's a per pixel operation, the question is, is the algorithm that's used, reversible ?

Ok, take a look at this http://img174.imageshack.us/img174/8440/testlq0.jpg[^] That was selecting the pinkish colour with variance of 100, hue +80, saturation -60 in photoshop. It may be possible to reproduce this in code but it could be diffucult and you could end up swapping the wrong colours etc. The real problem may be that if it swapped blue with green, but left green alone - you would not be able to set all the green back to blue because that would affect areas that where meant to be green in the first place. If you don't can't/can't be bothered to edit the pics manually, then I wouldn't mind helping out. I have alot of free time between now and the end of July EDIT: After thinking about it a bit more, in that image it seems as though the grays have been replaced - which is good because you should just be able to desaturate the affected areas without messing up the colour too much, this may turn out OK.

The hitch is that colour substitution is not reverseable. If you change all of the green to pink you cannot simply change all the pink back to green because it will include all of the pink in the image, not just the stuff that used to be green. Ultimately you can play around with curves etc. in Photoshop, but the net result is that the images are going to lose something. If I were in your boat I'd convince the parents-in-law of the coolness that is black and white photography and just have 'em all printed that way. :-D Cheers, Drew.

I think black and white is probably the way to go. There are some good articles on how to play with the strengths of the conversion of each color channel in photoshop so you can get some really stunning b/w photos out of basic color photos.

Why not email Canon's tech support for advice? OK - it probably won't get you anywhere but it won't hurt to try.

Convert the images to grayscale, which should correct most obivous color replacements, then recolor with software. I've seen that done to b/w photos, so it should be possible with grayscaled images as well. Could take a while, though....

Thank you for the good advice. As you suggest, they may have replaced x with y, leaving more y in the picture than originally and thereby leaving us with a photo where the changes are irreversible. I'll try and contact Canon and see if they can help. If you have enough free time and feel like trying, you could record the actions as a macro in photoshop, and I could process the remaining images. I sense that you sort of know what you're doing in photoshop - I don't :-D Thanks for your help so far! /Jan

yeah... sort of the answer I expected but hoped not to get :-D Do you think it looks like a simple channel swap?

Well, in your case it should work out fine since the tonal value of the new colour probably isn't that different from the old one. Something like Picasa or any other photo manager will work fine for converting those pics. Cheers, Drew.

Unfortunately I can't really offer much more then googling photoshop greyscale tutorials. Photoshop offers so many options to play with. Essentially converting to greyscale gives you more freedom to play with the color channels to create more dramatic effects. If you crank the blue sky unrealistically dark in a color photo it looks fake, but in b/w it might just look more dramatic. The way to do that dynamically is to do it with two or more layers, the top one converts to b/w and the others let you play with the colors, contrast and the like.
