Someone tell me why I need photoshop. I feel I'm missing out by only using Canon DPP. I think I'm intimidated by PS since I've never really used it. I only want to do basic editing, but I get the feeling PS offers a whole lot more "basics" than DPP. And yes I always shoot in RAW.
You can download a full-featured free trial of Photoshop, or you might consider PS Elements since you are evidently new or inexperienced in post processing -- Elements is less complex, less packed with stuff you will likely never need. Since you shoot Raw and are already using DPP, you likely won't see a big need for the full featured Photoshop, but may benefit a lot with the inexpensive Elements.
The advantage of having a decent image editor with advanced features, such as having the ability to use layers, selections, and layer masks, is that you can do a combination of selective processing (woking on one piece of an image one way and the rest of an image another way or ways), the ability to save edits in multiple layers so you can revisit your work on an image at any time, the ability to save the original image as a background layer so that any work done on it is non-destructive, and more powerful tools such as noise reduction and sharpening that are available to a "normal" image-level editor that are typically only available to Raw editors as external editors or plug-ins where an image has to leave the Raw format in order to be worked on. Also there are specialized areas such as HDR and exposure blending, plus panorama stitching that are only available to image-level processors.
That's just a nutshell of advantages. If I were you, I'd read up on these ideas as I was also learning to get the best out of my Raw processing. The more experience and skill you get in processing your Raw files, the less you will need to resort to an image editor. But, brush up on at least the capabilities of PS Elements so you can be aware of the steps further you can take when it will bring the best out of an image.
