Photo Tips - Color balance & Contrast

If you've ever taken a picture indoors you know that the type of light (flourescent/incandescent) can make a huge difference.  What I run into, more often than not, is a picture that is too blue or too yellow/orange -- all because of the unflattering indoor lights.


It's obvious what's wrong with this picture.  It's yellow. 

The fix is simple, although not every yellow (or blue) image can be resistated.

  • Open the image up in PaintShop Pro
  • Adjust
  • automatic color balance

  • Strenght = I default it at 32
  • Illuminant temperature - if you go right, it turns "bluer".  If you go left, it turns more orange.  In this case, there's plenty of orange/yellow, therefore it only makes sense that we go right, towards the cooler/blue side of things.
  • Slowly move the slider to the right, and you'll start to see minute changes
  • Temperature = that changes as you change the slider.  It's great to remember a specific number as a default.  Mine's about 6085. It's just the numeric spot on the slider.
  • Remove color cast = once you get the slider to where you think it should be, go ahead and either checkmark, or uncheckmark the box.  It will change the picture.
  • play with all the settings. One will work.
  • Hit "ok" to apply
After all is said and done the changes I made to the picture were:
Temperature: 7989
Color cast removed : checkmarked
Strenght: 32



From there, I'm going to go ahead and open it up (after saving it) in Photoshop to brighten the picture up some, and bring out some of the detail that's hiding.


Then I'll bring it back over into Paintshop and add a bit of color to it (for depth), crop it to size.

What I am missing from the photo is a bit more contrast.  I'd like it a bit darker and places. To do that in Paintshop:

  • adjust
  • brightness/contrast
  • brightness/contrast
Yes, it's in there twice.  I don't like using the automatic brightness/contrast so I do it manually.

  • brightness = numbers range from -255(black) to 255(white).  0 will leave the picture in the state that it currently is. If I want it a bit lighter, I bring the numbers up slightly.  In this case I don't want it lighter or darker.  So I'm putting the number at 2 for a mild lightening.
  • contrast = same thing with the numbers except that -255 turns it grey and +255 inverts the colors to make a negative effect..  I want to increase the contrast, but slowly. I'm going to try a 10 and see if that works.
  • Hit "ok" to apply when you see something you like
I'm then going to sharpen the image to bring out some more detail and save it.

In all reality, that wasn't the best picture to use - I just honestly couldn't find one in my deskmess (ie: computer jumble).  Getting ready for the new semester and everything's a mess :)
