When designing for clients, they are sometimes stumped as to what file types mean! Here is a brief diagram of a business card for a make believe photographer that will hopefully makes things a little easier.
PNG images are great when you need to use them for transparent items, for example, when you see logos on websites, or maybe on your Facebook timeline when you see a photographer’s logo on top of a picture. For watermarks, PNGs work best, and will often be used at a lowered opacity so that they can be placed on top of the picture. (my watermark of the white mouse is set to white with a drop shadow at a lowered opacity). Also remember to use PNG when you are saving a file that has a glow or drop shadow.
JPG images are probably the most common, but unfortunately, do not export the transparency. JPGs work best when you need to save a photo. If you were like me, you may have had that annoying problem growing up when you wanted to use an image from Google for a project, but there was always that white behind it! Jpg’s also work great when sending the final format, and also for when you want to use an image for a facebook post that may have gradients in it.
