Images for web or print usage frequently require adjustments from an upload, scan, or high-res photography to best prepare the images for display. Despite the improvements in image capture technologies there frequently is a need to adjust images brightness, contrast, color, saturation, sharpness, aspect ratio, and resolution for displaying the best possible image.

Image Brightness Adjustment

Some images are simply too light or dark all throughout the image. Altering the brighness will alter every pixel in the image to make it either lighter or darker.

Image Contrast Adjustment

Other images are "flat" or "harsh" in appearance. These images can be improved, sometimes dramatically by adjusting contrast. This type of adjustment makes the darker parts of images even darker and lighter parts of images even lighter or just the opposite by muting the darks and lights. The overall effect is to add or reduce "pop" in an image.

Image Color Adjustment

Particularly with art reproductions colors in the image created from an original don't match the colors in the original artwork. Even the best scanners and cameras don't consistently capture all of the original colors. Sometimes the starting image is a bit too warm or cool. Other times many colors are fairly close except one or two colors which don't match the original well. Some originals have metallic areas such as gold, silver, or copper which aren't true colors and need special care to best approximate their original metallic appearance.

Image Saturation Adjustment

Saturation is a measure of the amount of color in an image. The color may be accurate, but the saturation isn't correct - the appearance of the color is too pale or too dark. Some scanners and high-res photographic image capture will interpret certain colors with a certain saturation and other colors with a different saturation. Other times the entire image is either unsaturated or over saturated. Older photos and art tends to have less saturated colors so some software which attempts to automatically correct for saturation ends up over saturating the image. If the image capture isn't done with a sufficient amount of light, the resulting image can have unsaturated colors.

Image Sharpness Adjustment

You may notice that with some images the entire image is in sharp focus. With other images the intent is for some parts of the image to be in focus and other parts to be soft focus. With low-res images in particular that need to be enlarged for printing, care must be taken not to over sharpen or under sharpen or otherwise "pixelation" will occur. If an image is expected to be reproduced on some media such as canvas, sharpening can improve the apperance since the media itself naturally creates a softening effect.

Image Aspect Ratio Adjustment

The aspect ratio is the width divided by the height. For example an aspect ratio of 1 to 2 means the height is double the width. Another term someimes used interchangeably with aspect ratio is the proportions of the image. Image capture via scanners or cameras can alter the aspect ratio. For example, if there is extreme reflection on an original that is being photographed, tilting the image can help remove the reflection, but then introduces an error in the aspect ratio. For scanners, once the image is cropped digitally, it is also possible to introduce an error in the aspect ratio. To main the retain the correct proportions of the original, the aspect ratio of te image needs to be adjusted to reflect that of the original.

Image Resolution Adjustment

Image resolution is important for presenting an image that appears to the eye to be visually pleasing. If an image has a resolution that is too low, then the image will appear less sharp and even a bit blurry because there aren't sufficient pixels in the image to represent the image. If the image is overly high resolution, then for images on the web, the image may take too long to load. If any image needs to be enlarged, care needs to be taken to preserve the details of the image by maintaining a sufficiently high resolution. Some images are too low in resolution to enlarge beyond a certain size or otherwise "pixelation" will become very evident.
