Hi Retouching gurus

The church ceiling in the attached photo was obviously lit by 2 light sources of different colour, causing a blue cast at one end of the picture. I'd really appreciate it if someone could help me with a method to get a white background overall. I have Photoshop CS2 but I'm a new user. I can deal with straightening it on my own!

Many thanks,

Larry

I don't have a calibrated system here at work, but this is a prime example for the removal of color cast via Lab mode in Photoshop.

Here is another way to retouch this image. It basically involved selective: color desaturation, burn/dodge of shadow-mid-highlights, color replacement via painting, sharpening,

Do a dodging of the background area you want to lighten

use magic wand to select the monotone area you want to add color. Then use the select similar function in the select menu. Use eyedropper to select a gold tone from your image

Select a paintbrush with a 3 -7 opacity and paint over the monotone areas.


Then finish your retouch with selective burn dodge saturation sharpen.

Many thanks to Gale, Jeremy, Iliah and Robert for replying.

Robert, I'm amazed at the detail you took the time to provide. It's just what I need, given my level of experience with Photoshop.

I'll give it a go and let you know how it turns out.

Cheers,

Larry

Hi Gale

My monitor isn't calibrated so I don't really know how to answer. I think if you look at the gold and red in the area with the white background colour in the original I posted, you won't be too far off. I think the reds have probably faded from when they were applied about 300 years ago!

Cheers,

Larry
