atkkate,
welcome to
RP.
i had a go at this one, but i warn you, it's pretty far gone where it's been bleached out. bringing out very much detail is going to be difficult. nonetheless, it's not all bad. you can make out some stuff under there.
i'm not posting all that i did at this point. it was extensive and i've already spent a lot of time on this, so i'm not going to write it all up, even if i could remember it all.
i didnt even try to fix the left side over-exposure parts. there was nothing really there worth saving. i'd just crop that out. i'd also just crop out that black border. you could add any other border or frame back when done. so, all those parts are just in your way when fixing things. i left them in and ignored them.
i may also work on this some more later on. it could be better than what i've done so far. so bear that in mind also.
mostly, this is a challenge of contrast, lighting and color balance with a bit of reconstruction thrown in also. and you may want to split the channels and try to fix each individually. i didnt, but i did look at them. the red channel is the worst.
also, i dont know how familiar you are with all the tools and terminology of photoshop or paint shop pro or whatever you happen to be using, so i'll also wait till you've responded to give more details of what i did.
it's a difficult image and if this is your first attempt at restoration, you've picked a doozy.
in brief, here are some of the tools i used on this:
adjustment layers: contrast/brightness, curves, color balance, hue/sat (mostly just to look at the saturation layout)
filters/plugins: black and white points, smart fix, lum frequencies, digital camera noise removal, hue map (again, mostly to check saturations)
brushes-tools: clone, push, hue up down, saturation up down, lightness/darkness
the trick is to bring down the light but also bring out the contrast for detail and then color balance the whole while restoring some color in the bleached area. for the restoring of color i used a blank raster layer and airbrushed in various parts, including sky, foreground-beach, background trees, various flesh on the people, and hair.
parts of the image had to have their own selections and reconstructions-restorations. blending was then done to smooth corrected areas into the rest of the image.
all in all, a most difficult image. perhaps others will take a shot at this as well. Flora seems to have a good technique with images like this. maybe she'll give it a go.
