Hi,
I am a new member of this group as well as in the photography world. I just got a Canon T1i and I am trying different ways of shooting nice pictures. I read a tutorial on reverse mounted lens by one of the members. I tried but.... I cannot see anything (the object I want to photograph). I got closer and far but no success in any of the cases. Any idea want am I doing wrongly?

Thanks a lot

What lens are you using?

Also, when you say you "can't see anything", do you mean it's black or do you mean it's all fuzzy?

usually this indicates a need for more light.... If you don't have absolutely ridiculous amounts of light, you're probably underexposing severely. Macro demands tons of light.

Are you using the lens that came with your camera? If you are, then you are out of luck. Modern lenses keep the aperture fully closed when they are not mounted on the camera. And, since Canon lenses don't have an aperture lever, you have no way to open the aperture manually.

You need to find an old manual lens where you can set the aperture on the lens, or you need to find a modern lens that has an aperture lever (you'll need to hold the lever to open the aperture while shooting.

I think I read somewhere about a trick of setting the aperture with the lens in the normal mounted position, and then take it off the camera without shutting off the camera. I thought someone said it would hold that set aperture. I'm not going to try it with my camera to verify though.

Yes, you can depress the DoF Preview button to stop the lens down, then while holding the button, remove the lens. The aperture will remain stopped down.
To correct an earlier post, the aperture on modern lenses is held full *open* until the shutter is tripped, then stopped down, and re-opened after the exposure. So when a lens in removed under normal circumstances, the aperture will be fully open.
For the OP, you will find that the subject distance is *very* close to the lens when reversing a lens. In fact, I'm not at all sure that all lenses can be used reversed. Reversing will work better with shorter focal length primes. Try a 50/1.8 and see what kind of results you can get.

I'm using a Canon EFS 18-55 mm. The viewfinder gets completely black unless I am focusing a lamp. I am going to try with much more light.
Thanks a lot

Fritz is right- not all zooms work reverse mounted. They may work better if you reverse mount them with a close up filter attached, but these close up filters have their own issues, of course. Be aware that when he says *very* close, he means somewhere within a couple inches of the element.
The 50 works well- you can even just handhold it without the reverse mount coupling ring to see what sort of results you'll get. You can also stick the 50 (or whatever else) on the end of another lens, reversed, to get some super close magnification.
It's odd that things are completely dark though... look through the back of the lens and see if the aperture is open.
