Problem with Brightness/Contrast

I'm stump with this photo (first attachment)! Tried everything I know to adjust the brightness and contrast.

The last attempt (second attachment), I converted the duplicate file to lab mode and adjusted the lightness. Then copied the image back to the rgb original, lowered opacity to 70%. Still not satisfied with the result.

I'd appreciate all the help...thanks.

Soleah, your green channel was severly underexposed with no detail in a large area. I used the channel mixer to replace it then used a Hue / Sat adjustment to adjust the color to where the skin looked normal and door in the background was more neutral. Since I do not have a reference to go by, I may be somewhat off where I left it. The image you uploaded is very pixelated due to jpg overcompression. I assume that you have a higher quality original and therefore won't have those artifacts on your version.
Regards,
Murray

I did a shadow/highlights adjustment, made 2 dupe layers; one mask layer for woman and child and one blured with a gradient mask to give some depth and kill off colour noise in the corrected shadows. Also added a warming filter layer with same gradent mask to correct cyan colour cast. It is a bit rough and ready but I hope you get the idea.

mistermonday, I didn't bother to look at the individual channels, I missed that step. Thanks.

littlecoo, does the shadow/highlight adj layer have an equivalent step in PS7? I also want to try your idea.

Hmmm...levels and curves adjustments with some masking esp of the woman and child is the closest equivelent I can think of. Sorry about that, I never possessed ps7 so I do take the capabilities of CS and CS2 for granted... not knowing any different.

Hi,

soleah,


haven't 'seen' you in a while... How are you?

I don't know if this is in the right direction ... To lift the shadows, I selected them and used a single Levels Adjustment Layer set to Screen on the selection... (the immediate result after this procedure in Attachment 2) .... Let me know if you'd like more details...

P.S. I changed the colour of the floor because I saw you had done it .. but after brightening the image the floor colour is burgundy ...

Hi Littlecoo,

great idea for the mask!!! Thanks for sharing!!

Unfortunately the great Shadow/Highlight Adjustment Layer Option is available from PS CS upwards only ...

nice work, all.

i saw this image and because of what i'd been experimenting with in filter forge, i decided i could make a filter that might do the job here. it basically splits the foreground (read: lights) and the background (read: darks) and then treats each separately as if they were different channels. you could probably do this in filtermeister too.

anyways, i tried several variations, trying not to move the threshhold so far as to cause parts to fade to translucent. it worked fairly well. here's 3 versions.
