I process a large number of images submitted for printing and am saddened to see quality issues that could have been avoided with a simple change to a camera setting. Here I summarize my recommendations for the most important settings. See my blog article for more details.
Setting resolution (image size) as high as possible and holding the camera steady will help you get large prints that are sharp. With dropping prices of memory cards and external disk drives, saving space is no longer a good reason for lowering the camera resolution. You can spend more on one large print than an external disk drive that will hold many thousands of image files.
Set to the highest jpeg quality setting. Again, saving space is not worth the cost in poor prints due to jpeg artifacts.
Advances in software have made it easy to process raw files. Using them and staying with 16-bit images will pay off with good prints that have lots of highlight and shadow detail and no posterization. I recommend Adobe Lightroom for fast and easy processing of large numbers of raw images from your camera.
ISO, the equivalent of film speed, should be set to automatic or as low as you can consistent with obtaining a good exposure that has no motion blur and enough depth of field.
With the latest digital cameras, automatic exposure works remarkably well. However, it is important to avoid over exposure of especially white objects such as clothing, snow, and clouds. Using your camera’s histogram and “blinkies” setting can help you avoid over exposure that prints as pure white without detail and texture.
Using the best color space is not as important as the other settings above, but changing from sRGB to Adobe RGB in your camera will allow you to capture more colors that you can expect to be reproduced in the print.
