New Member - improving dark cast on photo

I found this website a few weeks ago and I'm looking forward to spending more time here. Everyone seems very helpful and friendly! I currently use Photoimpact and have also used Photoshop Elements for my graphics editing. I would like to learn Photoshop in the future.

For my first post I thought I would ask for a little help. I have approximately 10 photos from an event that need enhancing. I have scanned the pictures using an HP6200C. Several pictures have a dark cast on the right side of the picture. What would cause this and more importantly, how can I edit this?

Also, for photo improvements in general, in what order should editing tasks be carried out?

Thanks for your comments!

Mona

If the original photos didn't have the color change, more than likely you had the edge of the photo right up against the edge of the scanner.

This can cause the picture to slightly raise off the glass, or to be slightly outside of the bulbs lighting area.

If that is the case, I would just rescan them with the picture more in the center of the glass and see if that helps things.

Hi Noel,

Unfortunately the originals do have the color change so it won't be as easy as a rescan. Thanks.

Ah, that makes it a little more difficult then

Ok, I'm not positive how this works in Elements, but I'm going to give you the Photoshop answer.

I would copy the layer, make it a lighten layer. Then using a gradient mask on the lighten layer, I would basically only lighten the area that is affected. (example 1)

From there I would use the clone brush to take care of the sky, and some of the trees and then darken it up a little from there.
(example 2)

The below is very quick and dirty. If you spend a little time on it, you can definitely make it look much nicer.

I'm fairly certain something similiar is doable in Elements, someone with more experience in Elements can probably chime in and say so

Not being familiar with the software you are using, I would make this suggestion:
Look through the restoration challenges, for an image that has a similar problem as yours.
Check out the members work to get an idea about how they fixed it (most write full descriptions of how they did the repairs).
Having that information, if you are experienced with your own particular software, you could translate the steps used, into ones that will work in your program.

Golf Course

Hi Mona,

I am not an expert here Mona, but this is what i did in Photoshop for this picture.
Used clone for sky and part of the tress and grass
Selected the sign and used a hue saturation on this
Used unsharp mask to make the final adjustment
Hope this help somewhat, maybe someone else will jump in here that is alot better than i am.

Hi All,

Thanks for the suggestions about the photo and for taking a stab at improving it. The picture was taken in a southern state so I'm not sure how green to make the golf course. I'd like to keep it as realistic as possible. Is there a way to tell if one color channel over another is dominating things? Also, I've included a screen shot of the levels screen below. Why is the histogram so flat looking? What does this say about the picture?

Thanks,

Mona

* I added a second screen shot of the blue channel. The red and green channel were the same as the master.

Hello,

I posted a message early this morning and it is no longer here. I also posted two pictures and now they are attached to another person's post. What happened? Does anyone else get the golfcourse photos when they click on the photos in the next post? Can this be corrected?

Thanks,

Hi Mona,

I got to see your 'vanished' post and I actually wanted to answer (you were asking about fixing the sky....) ... but when I logged on again, your last post was gone .... I thought you had changed your mind and deleted it....

Let me try to find out what happened...

Hi Mona,

... me again .... It seems that what happened to your post and pictures is a direct consequence of RP's announced move to a new server....

There shouldn't be any more 'weirdness' now ....
