Removing Colour Casts (1 Viewer)

Hi,

Not really sure if this has been posted in correct forum.

My question is, how can i remove colour casts from my images? Basically im noticing a rather yellowing effect across them. This only seems to affect my digiscoped images. I use Photo Elements 2.0 and also have Photoshop 6.0.

Thanks for any suggestions,

Tom

Hi Tom,

I am not very experienced with image editing, but in my experience these actions could be worth trying:
1) Image->Adjustments->Auto levels/colors
2) Image->Adjustments->Variations (then choose the one which looks best)
3) Image->Adjustments->Levels-> choose the white eyedropper and click on a detail which should be pure white.

I'll let the experts suggest more elegant tricks.

Hi Ilkka,

Thanks for taking the time to reply, and for your suggestions.

I will spend some time reading over and experimenting with what you advise..... :)

Thanks

There are a gazillion tools for correcting color casts in Photoshop and probably other programs as well. You can use "Curves" and "Levels" on individual RGB channels. But I tend to use the "Color Balance" control.

However, you might want to try fixing the problem before you have it by doing a white balance preset through your scope with your camera. This way, the camera will do a major chunk of the color correcting for you and will do it using the information rich "raw" data from the sensor. Then you only have to do minor tweaks in your image processing program.
 
Hi Jay,

Ive started to discover some of the tools available. Weird, but its only fairly recently i have noticed these particular casts in my pictures.

Tweaking the white balance preset for my camera and scope is an excellent idea. I'll give it a go.

Thanks for the suggestions.
