t._duane_jones Posted January 18, 2006 Share Posted January 18, 2006 Hey everyone,<br>I am posting an untouched negative scan from a previous wedding. I chose this one because the color doesn't look the way it should. The prints from the lab look great, but I would like to know how to do it at home. Could you offer advice on techniques in PSCS to make the color look more natural? I am trying to learn more about color correction using PS with negative scans. Thanks for your advice.<br>Duane<div></div> Link to comment Share on other sites More sharing options...
alan_chan4 Posted January 18, 2006 Share Posted January 18, 2006 You may try the neutral gray eyedropper in Curve or Level as a start. Link to comment Share on other sites More sharing options...

cbender Posted January 18, 2006 Share Posted January 18, 2006 Something like this? I did a very quick adjustment of the midtones using the Curves dialog. I decided to make the shadow in the brides dress neutral (which it probably shouldn't be). I dropped the green curve so it's level at my chosen 'neutral point' matched the red curve. I also raised the blue curve, although not all the way. Raising the blue to also match made the image too cold for my tastes, so I kind of comprimised about half way. Keep in mind that I'm doing this on my laptop display that is not calibrated, so what I'm seeing may be completely off.<div></div> Link to comment Share on other sites More sharing options...
alan_chan4 Posted January 18, 2006 Share Posted January 18, 2006 I used the "set gray point" (in Level or Curve) to click on the suit then clip the white point a little to increase contrast. Your 2nd picture looks a little too much magenta. Link to comment Share on other sites More sharing options...
t._duane_jones Posted January 18, 2006 Author Share Posted January 18, 2006 Thanks to everyone for their help. <br>Eric: I have been reading the tutorials available at Creative Pro's website.<br>Alan, that looks great.<br> Any other books or websites you recommend?<br>Thanks,Duane Link to comment Share on other sites More sharing options...
EricM Posted January 18, 2006 Share Posted January 18, 2006 The Scott Kelby book for digital photogrpahers is great, i like the easy reading style. He'll go through step by step on setting up your eye dropers (values and size) in curves and explaining where to sample from. Link to comment Share on other sites More sharing options...
alan_chan4 Posted January 19, 2006 Share Posted January 19, 2006 After checking some CS2 books, <a href="http://www.amazon.com/gp/product/0240519841/qid=1137649101/sr=1-1/ref=sr_1_1/102-0603940-7152968?s=books&v=glance&n=283155">this</a> is what I like most. It goes through the basics instead of filling the book with tricks. Link to comment Share on other sites More sharing options...
jasonsmith Posted January 21, 2006 Share Posted January 21, 2006 Scanning colour negative film is often problematic as the film often has a colour cast. One way to tell if your image has a colour cast is to run the eye dropper tool over a a part of the image that should be white. The RGB values should be fairly similiar. If one channel is higher than the others it will indicate a colour cast. The first step I take is to go into levels, or curves and set the highlight/shadow points. This will normally take care of any colour cast. I have done this with your image and increased the brightness a little. There are lots of good books out there which will explain this.<div></div> Link to comment Share on other sites More sharing options...
fotografz Posted January 21, 2006 Share Posted January 21, 2006 What has to be understood is that color cast is directly linked to exposure levels. A shot that looks decently exposed but has a strong warm/yellow cast to it will look darker when the color cast is neutralized. This makes getting the white balance as close as possible in the camera even more important ... especially if you're shooting higher ISOs. When in PS correcting RAW files, it's best to neutralize the white balance first to see the true levels of exposure correction needed. PSCS2 ARC offers quite a range of exposure controls to correct a file, but it needs to be the color temp you want first. Once corrected you may wish to slightly tweak the temp to taste again before saving. Link to comment Share on other sites More sharing options...
