Is Editing Digital Photography Images Safe for Image Quality?

Posted on | April 22, 2009 | No Comments

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. The image is stoked onto your hard drive in a compressed format, named JPG. 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. When you save the image, if you choose the option JPG, the memory image will get compressed using the JPG algorithm, but the image will still remain uncompressed in computer’s memory and it will reflect the original image along with all the processed changes you brought to it, without losing any information through the saving process. Only the saved JPG has less information because of the compression, what is located in the computer’s memory is unchanged as long as you save the file under a new name.

It’s normal to make intermediary saves when changing a photo’s appearance because you never know what could go wrong. But when making these saves, be sure you make them under a digital photography format that does not only allow you to keep the image quality but can also save the image layers you might be working on. The best thing is to choose the format that is recommended by the editing software you are currently using. 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 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. photo printing online
