Is Editing Digital Photography Images Safe for Image Quality?

Posted on | April 22, 2009 | No Comments

People are usually afraid of working of plain Jpeg on their PCs after they collect them in that format from their digital photography apparatus, and are inclined in directly transforming them to tiff.

But transforming from JPG to something else has no relevancy as a first step of editing digital photography. The images downloaded from the camera might be a compressed JPG that will be stored on the hard drive. The image that is read by the virtual memory is uncompressed. deciding if you want a jpg or png or tiff or other extensions should be a worrying matter only when you are prepared to save the changes. If the editing programs remains open, and you make a tiff save, the computer will use tiff compression methods to save a copy on the hard drive, but the original uncompressed image in still unchanged. The only quality changes are visible in the saved JPG, with because of the compression it’s normal to have less information.

This problem is questioned by people that make saves during editing so they have a good restoring point that can show some progresses. Make the intermediary saves in a digital photography format that stores high quality, maybe even uncompressed images , but also leaves the edited file intact, without flattening and closing layers. If by instance you are using Photoshop to make changes, then save the intermediary files as psd, witch is the typical Adobe Photoshop format. This way, all changes become editable and reversible when you open the saved image again. And finally, when you think you are done, choose a final saving format for the image from the conventional ones.

Another myth that is not true is the one that states cropping a digital photography image can modify its pixels. Cropping means that you can rotate, enlarge, resize the picture using certain algorithms that are known by your editing program. There are shrinking algorithms that eliminate extra pixels, and enlarging ones that make the pixel dots bigger. snapfish review
