Customer Question

Hello, I'm trying to learn my Canon 70D. All of a sudden (after I changed to RAW plus JPG), every picture I take is completely blacked out, no light whatsoever. Can't find anything that will change it. It's set to 250 shutter speed, 100 ISO, aperture 10.

Correction: Completely black screen in Manual Mode, which is what I'm trying to learn because when in Auto, it shoots average 6400.

Hi, thank you for contacting My name is Russell. I will do my best to provide the right answer to your question. How new is your camera? it might doubtfully have a defect and need exchanging or returning. But, there is considerable hope that the camera is OK. Check your aperture settings, your ISO settings, etc. The exposure level may just plain be too low - resulting in the preview image being black. This is confirmed if you get a Preview picture that is visible on the screen, when you press the shutter button half-way.... in that case, the picture is made bright enough to see, by temporarily ignoring your aperture and ISO speed settings, but the black picture is the true preview and the picture will come out grossly underexposed if you take the picture. So, I think it might just be a matter of settings. Try a larger aperture and/or a less extreme ISO, and you may get better results. Let me know what happens.
