welcome lqdwax!

flora has a good way of doing these, but i forget where it is. i think there is one she did in this forum, but not sure which one. there might also be a tut in the tut forum. have a look around and if you cant find it, i, or someone else is sure to give it a shot.

Hi lqdwax,

had a quick go with your second image.

Selected RH half of your image using rectangular selection tool, copied and pasted to new layer. Adjusted levels to make darker, applied graduated mask to mask central area and darken just RHS.

Repeated for left half of image.

Applied levels adj layer to whole image. (Took down some of the blown out whites).

Curves adj layer to lighten LH figure.

merged layers, then applied USM to sharpen and up contrast a little.

Could do with local adj on remaining blown whites, but will leave this to you.

Hope this helps, gary.

I tried your picture out just for about 5 minutes, in between chasing my daughter around. I downloaded the free month trial for PScs2 to correct it. 1. But I selected the man on the let and used levels for him to brighten him up.

2.Then for the rest of the picture I used the shadow/highlight feature.

3.After that I didn't like how the man on the right face so I selected that and i used levels to brighten that up some.

4.Then i used the smart sharpen to sharpen it up some.

I usually use PS 6.0 and i think with that i would select each area that i didn't like after i used levels for overall picture. and use levels to brighten or darken that area, and mask out the edges of that. I hope I helped some.

I copied the background layer and added a radial-gradient layer mask, white in the middle, and set the blend mode to screen.

There was still some vigneting, so I copied my screen-mode layer. Setting the opacity to 70% got rid of the last unequalities.

The rest is adjusting levels and contrast, taking care not to blow the shirt or block the eye sockets.

nicely done, gary, jenjen, panpan.

the others worked on the 2nd one so i thought i'd give the first one a shot. this one is badly washed out at the top and bottom. i had to rebuild some of it with clone, but i that towards the end.

to start i added a contrast/lightness adjustment layer, one for curves and one for levels. i tweaked each of those for the overall and then used the 'edit selection' feature in psp 9 to build a mask/selection area across the middle. i used a gradient brush along the bottom of the treeline and built upwards on a gradient. this was also set on a fairly low opacity and with a 15 feather. i didnt want a harsh mark between the selection area and non-selected area. when i had the selection i used a contrast/lightness to lighten this area and give it some more contrast.

killed the selection and worked a LOT with the various global layers to even things up a bit more. i also used the lightness/darkness brush/tool to bring up a few dark areas.

and frankly, after that, i lose track. i made a LOT of adjustments here and there to try to get some detail in the top and bottom and even up the light/dark balance and bring out more detail.

and like i said earlier, there just wasnt any detail left in the very top and bottom so i cloned some in.

i did one last global contrast/lightness and that was pretty much it.

now, i wouldnt expect anyone to follow my rather haphazard 'instructions' there very closely. the idea was to even up the edges with the middle as far as brightness. that was the biggest part. the secondary part was to bring out some more detail if possible.

i'm fairly sure someone else could do a better job, but this at least gives you a way to start.

Craig
