Image Quality, Size and Resolution

[Kampar]

The good reputation of Customaniacs is due to the quality of the artwork on the covers and labels we host here just as much as to the quantity of them!

We often find, especially with new uploaders, that there is a misunderstanding about what is and what is not a high quality image. Comments such as "it's a 300DPI picture so it must be high resolution", or "well it printed okay on my printer" are something we hear regularly.

Well, in reality the term "300DPI" has no bearing on the quality of the image and what one member might regard as acceptable coming off their printer might not be quite as acceptable to another member with a different printer.

Therefore, we have produced a comprehensive guide that describes the difference between image quality, image resolution and image size and what to look for to decide whether an image is good enough to use or not. All of the major JPEG compression artifact types and common image problems are also described, each with a sample image to look at for reference.

The .rar file download includes a PDF tutorial document plus a number of accompanying JPG image examples.

Just as a teaser ... all three images below have the same resolution: True or False?
