  • CellPhone Image Color Cast

    I recently took a photo using my cell phone, now that I have it on my computer, it has a pink/purple ish color cast, and the subjects faces are blown out. Looking at the color channels the blue channel is by far the one that shows the most detail. Is there a tutorial on how to color correct via the channels?

    I have not seen a tutorial on it. However, if and when you do, getting the colors right again can be tricky. Most of us would not use the blue channel in that way. Rather, use it's luminosity in various blend modes just to reveal the detail more in the other channels using calculations (apply) or as an overlaying layer. Then simply tweak color as you would otherwise, or use variations to help you get there.

      Well regarding the color cast you can play with the levels. I did something like it when I scanned a negative leaving it like a color positive to make the conversions in photoshop to get the most of the "original" information without letting the scanner software do any changes to it where there was no real control of it.
      After inverting the colors I found out that the photo had a cyan color cast to it so I started playing with levels first closing the gap on each color channel which just from that helped allot with the color cast, later I played with the color balance and got it to my desired taste.

          color correction, color cast
          by javier
          Hi, some time ago I opened a thread as I was working on an old docment, and the main challenge was to extract the italics letter and make them readable. I had to play with layers and so on, as indicated by people in this group. Now that is OK, but the background color is an ugly brown.
          So my...

          Hi gang,

          How to correct this incredible color cast
          by bestremera
          This is a Photomatix exposure fusion (not HDR) composite of 3 exposures. I know I was going to get a crazy color cast so I put that white card on the floor hoping that clicking on it with levels/curves white dropper would fix the color. It didn't. It blew out all the highlights and a strange color cast...

          Help… Worst Color Corruption
          by Richard6911
          I’m being held hostage by the worst color corruption problem I’ve ever encountered. I can’t call Chris Tarentino – because he’d give me some mathematical formula I’d never understand. I can’t call Amy Dresser – because she’d advise me, “Try about 100 lassos and color curves.”...
