Different ways to save an image

There are many ways to save an image according to the purpose of it. Here I will explain the most common ways that you can use in 99% of cases.

To save the document for access it wherever you need to go to "File" menu and you'll have two options "save" and "save as". "Save" is used to either first save a new document, or to go keeping the progress of your work, quick shortcut Ctrl + S. "Save As" though it would be to save a copy of what you're doing with another name or another format, quick shortcut Ctrl + Shift + S.

Especially they will see two major cases. The first is to save the image in Photoshop format, with all the quality and all information that we have added, and the second case is to choose a suitable compression format image once you are finished with it, according to what the want.

Save image with Photoshop format.

Saving in Photoshop formats is always only for personal use (unless if you want to pass it to someone, of course), because they contain valuable information about your work. This format preserves all layers, the maximum resolution and all information that has been added to your job, which is a very large file (occupy much space on your hard disk). The PSD or PDD formats (it's the same) are the most common but there is also one for when working with really large files (such as billboards or plotter files), and this is the PDB.

Save image with a different image format

The most common image files are jpg, gif and png. They must be stored in these formats at the end of your photo editing, since this way you make sure that every computer can read your work done, and as we said before, so they do not see all the processes that have been made to the image. Then I explain briefly used for each of these image formats.

Jpg (or jpeg) file, is the most widely used today as it is the best "quality / size" is. It has almost no loss of resolution and lets you save all colors and all resolutions. I always use this format for normal photos but the only drawback is that it lets you play with the opacity, which if they do gif and png. Once you give us will keep this dialogo.

Here you can change the quality of the picture, when you put more quality, more will occupy. You can also select to progressive. This format is mostly used in web and serves to make the image gradually and not suddenly load. It will be used mainly for large images as in small, if we can save a few kb, much better because we'll only notice this effect.

PNG files are similar to jpg occupy more but instead allows you to leave the transparent image areas, which is useful in performing websites or magazine layout.

Images with and without transparency

And finally gif format are the least weigh (less kb deal) but is not recommended for photographs because it only has 256 colors and lose a lot of color information (note that normal images have 16 or 32 million colors), by which it will be used in logos or vector images with few colors.
