Is Editing Digital Photography Images good for Image Quality?

Some say that after you have your high quality, high resolution pictures and you want to put them on your hard drive and work on them for a little bit, it’s best to transform first the Jpeg files that come from you camera to tiff or other appropriate format, because working on jpegs might cause you to loose quality and color.
But transforming from JPG to something else has no relevancy as a first step of editing digital photography. Usually camera save pictures as JPG, and this is the format you will see on your hard drive But the Pc’s virtual memory will unravel the image when you open it. Only at the time you want to save the edited image from you PC’s virtual memory you might raise the problem of file format: jpg, gif, tiff, png and so on. Compressing during a save does not affect the quality of the initial uncompressed image with the changes it now has that is still located in the virtual memory and will remain there until you close the editing program. What you have in the computer memory is not affected by a save during editing, as long as you use a different name for the new file.
This problem is questioned by people that make saves during editing so they have a good restoring point that can show some progresses. These intermediary save will always be done under a format that is especially made for editing, that saves both quality and allows changes to become editable. So this basically means you should save the intermediary images in the format that is specific to your photo editing software. If you do this, when you mess up your work and return to the saved point, you will be able to follow all the previously taken steps. And finally, when you think you are done, choose a final saving format for the image from the conventional ones.
It’s a myth that circulated for a while and says that if you want quality pictures, the cropping is not allowed. Cropping results may turn up better or worse than the original, but it all depends on the functions used There are shrinking algorithms that eliminate extra pixels, and enlarging ones that make the pixel dots bigger. snapfish
