I have made some suggestions earlier on, but most beginners use software with a single focus to do most photo editing. There are several free photo editing software that do most of their job quite well.
Free Photo Editing Software for Beginners from The Photographer’s Eye has a nice interface and good color balance. The default options make it pretty easy and fast to take a photo with just a mouse or a button press. The only “gotcha” I would recommend is that there is no way to save high-quality pictures after they have been taken (even if the settings have been changed), because the pictures are always visible but the options available have a big “skip” button that would make it almost impossible to edit if you needed to save the original. All the pictures exported are in PNG format. The downside is that some of the options (even the ones you can easily change) can be a bit difficult to understand (and it’s not necessarily the easiest to learn) if you have no prior knowledge of software (or a lack of one). However, once you have a general idea of the settings, and know that you are taking a photo from the RAW file rather than with the usual “crop to size” and “normalize” options, it takes less than a minute to be able to crop a photo to a reasonable size (up to 8×8 or 2×2) using the free “R” file extension. You will need to do a background check on the PNG files to make sure they are OK, then use the “auto detect” and “save as” options to crop the picture to the desired size. The quality will increase a little as the quality of the output increases (in my experience with the free software, I would say that the quality of the default images is higher than the best quality photos, though). If you want a little more control to edit the image, look into photoshop. It’s free and works very well, but it’s limited in the number of editing options it has. You do have the option “create an effect”, but if you are going to try to do an image manipulation (such as retouching, lightening, and color correction), it’s more of about understanding the software and understanding what it’s capable of.
