Improve Your Digital Images While Shooting
There is no substitute for good photography. It is very rare that a poor photograph can turn into a good one with computer software tools. Besides, would you rather spend hours taking pictures or hours in front of the computer making corrections?
Since it is now so easy to adjust photographs with software, many people assume that they can always correct an image later. This is not true. You will have fewer problems in the digital darkroom if you can shoot well-crafted images from the outset.
Usually there are just a few things that cause a photo to not turn out:
Blur: This is usually caused by a shutter speed that was too slow. Blur is very hard — if not impossible — to correct in the digital darkroom.
Under- or overexposure: Overexposure cannot be corrected in the darkroom and underexposure often leaves an image looking muddy without much contrast or snap to it. Overexposure, especially with digital photography, will leave no detail in the highlights.
Bad color balance: This happens when the automatic setting did not see the light properly.
