Blotchy spots on my photos? I need help!!!

So these spots started showing up recently on my photos, and I'm 100% sure its not my lenses. I've snapped a photo then cleaned the lens and snapped another and the spots still remain. I switch lenses and the spots are still there in the same place. Could it be the sensor or....???? I'm completely clueless as to what this is. Do I need to send my camera body in? If someone has had this same thing happen to them or if any one knows what this is PLEASE HELP!

You have some junk on your sensor. It may be easy to blow out or it may need a more rigorous cleaning.

Read up on sensor dust. It may not be worthwhile to have cleaned. It will be apparent when stopped down.

Is it safe to blow canned (compressed) air into the camera body? Do I just lift the mirror and apply the air?

dust and grime on your sensor, nothing serious to worry about. do a search for cleaning sensors, you can also clone out that stuff in post.

Yep, just dust bunnies on the sensor. A fact of life with a DSLR camera, you clean 'em out and some new ones come along. A rocket blower should get rid of some of them, if not all, if they still bother you and there are too many to remove in processing then you will need to take further action (just google sensor cleaning).

Using a smaller aperture will make them more noticeable, and they may almost disappear with a wide aperture.

DO NOT BLOW COMPRESSED AIR ON THE SENSOR

GET A ROCKET BLOWER

look it up on google and you will know why!

Thats exactly what Ive been having to do. The thing is, I might be selling the body to someone and I dont want them to have to deal with the problem

Not a good idea. Canned air can spit out propellant gunk which is worse to shift than the dust. Rocket blowers are cheap and do a decent job.

if using canned air, make sure to keep the bottle level, or use camera specific canned air. i suggest reading up on sensor cleaning before doing anything experimental.

it's a never ending fight to eliminate dust (if you change lenses regularly), so i just clone them out or avoid shooting a super small apertures

Thanks, I'll google sensor cleaning and rocket blowers now...!

Dust on the sensor is a fact of life...the owner of ANY digital slr camera WILL have to deal with the problem at some stage and on an ongoing basis.
Simple as that.
