Photo Editors
exposes which functions are important and make a photo editor software convenient to use.
Digital Photo Enhancement
exposes many aspects of photo enhancement, the exposure and contrast correction,
the color cast correction, the sloped axis or sloped horizon correction and the sharpness improvement.
Histogram
exposes the role of histograms and how they can assist you for exposure/contrast correction and for color cast correction.
Gamma correction
exposes the way to treat photos that are too dark or too light and why gamma correction combined with levels correction
through the assistance of an histogram is faster and gives better results than common brightness/contrast correction.
Photo correction of geometrical issues
tells you how to correct a slanted horizon line or slanted axes very easily,
without guessing if the inclination of your horizon is 1 degree, 2 degrees, 5 degrees or whatever.
Also treats about barrel and pincushion corrections.
Sharper Image
exposes the way to give your photos a sharper look without the inconveniences of the built-in sharpening tools of most editors.
Batch Photo Enhancement
exposes the ways and limits of exposure/contrast enhancement and color cast correction through a batch process.
Resizing photos
exposes the difference between simple resizing and resampling -or resizing through a resampling algorithm-.
Resizing jpegs
exposes why jpeg images are easy to resize through a resampling algorithm.
Resizing gifs
exposes the problems encountered when resampling gifs and how to get around them.
Converting images
tells you how easily you can convert photos from one image format to another one with nearly any photo software.
Converting bmp to jpeg
exposes how easy it is to convert from bitmap to jpeg with nearly any photo or image software.
If you only need to convert from bmp to jpg, skip the page above and go straight to this one.
Image Viewers
exposes which functions are important and make an image viewer software convenient to use.
Batch Software
tells you which photo editors and image viewers will let you apply the same treatment to many photos in a glance.
Batch image conversion
lists photo software that is able to convert images via a batch process.
Batch image resizing
lists photo software that is able to resize images via a batch process.
Batch Photo Enhancement
exposes the ways and limits of exposure/contrast enhancement and color cast correction through a batch process.
Mentions a software that enhances photos via a batch process.
Photo Album Software
exposes what photo album software has more compared to photo viewers and lists some photo album software.
Animated GIF photos
tells you how you can make animated GIF files with your photos.
Photo & Web site
tells you what to care of when you write a page containing photos.
How to rename file extensions
explains how to rename single file extensions and how to rename file extensions in a batch if they have been changed unexpectedly.
Resizing versus Compression
explains that photo resizing and photo compression are 2 different things and shows examples.
Examples of photos.
Compressed photos
shows examples of photos compressed with various quality factors.
Enlarged photo
shows an example of a photo that has been reduced and enlarged again leading to quality loss.
