What Everybody Ought to Know About 10 Photo Issues and How To Avoid Them

1. Purple Fringing

– one of the most commonly chromatic aberration in photography

Try not to shoot against the sky if the below portion of the frame is much darker, decrease the exposure one step, use a polarizer and, if possible, shoot in RAW format.

2. Overexposed

– too much light enters the camera in a given time

If this happens, adjust the exposure setting with -. (This can only be done in Program, Shutter Priority and Aperture Priority Modes.)

3. Underexposed

– too less light enters the camera in a given time

If this happens, adjust the exposure setting with +.

4. Pixelate

– very low number on pixels on a fairly large area due to the use of high digital zoom

Never use the digital zoom. (Normally it can be turned off in the camera menu)

5. Overall Motion Blurriness

– caused by shaky hands

Use a tripod in low light conditions and shutter speeds longer than 0.5 sec.

6. Red-eye

– when the flash light is close to the lens (compact cameras)

This can only be avoided by in-camera software red-eye remove – sometimes it might not even be effective.

7. Lens Flare

– It happens when shooting against the sun and it is more visible with SLR cameras due to the lens construction

This can be avoided by using a hens hood.

8. Too soft

– usually this happens when digital noise reduction is used and the subject is out of focus

Be careful when focusing (like don’t shoot landscape in macro mode and vice-versa). Usually, SLR cameras create sharper images than compact cameras do.

9. Over sharped

– too much sharpness creates unrealistic edges

When sharpening an image taken with a compact camera, try not to push the sharpening over the aesthetic limits: keep the edges without a light hallow.

10. Uniformness noise

– high sensitivity used in low light causes chromatic not uniform noise which should not be compared to the uniform black and white grain that appears on film photos or added as an effect in Photoshop

If you’re shooting a night scene, use a tripod and longer shutter speed instead of high ISO. When shooting portraits in low light use the flash instead of very high ISO.

Note: I’m not including here vignetting and distortion (caused by using some wide lenses at the limit), even uniform noise (grain), since these, if used rationally, can produce creative images.
