I have a digital SLR Nikon D100 My cousin is very camera savvy...I asked for his advice on how to get a spot off of my mirror. He suggested spraying air on the mirror. So..I did...Now my auto focus isn't working. When I switch my lens to manual mode, I can take a picture...but when I switch it to auto...it doesn't even click. It wont auto focus at all.

Depending on the type of interchangeable lens you have mounted on the camera, there may be a switch on the lens barrel for choosing between auto-focus or manual focus. The N55 also will not auto-focus with the newer Nikon AFS lenses such as those used with the Nikon D40 digital slr. Finally, there was a service bulletin on the N55 back in 2005. Nikon discovered a problem with the auto-focus and fixed it for free, but there may have been a time limit. Here is a link to more info about that:
Change your focusing setting to spot focus. Then, focus on your main subject, keep the button half-way pressed while you re-compose the shot and then press it the rest of the way. Does that improve the shot?
I think you have 2 problems at one time.
1 - I notice that your depth of field is very narrow, (your aperature is quite open) which hardly can focus the spot you want. try to increase the f/number like f/4 or above. the models face and there clothes toward your nikon D100 is almost the same distance, so they should be in the same focus range, but as I said witch big aperatures like f/2.8 of f/1.4 every inch count when it becames to focus.
2 - Set your camera in Single-focus (not Continous focus) en focus on the models face. then press halfway en keep it pressed. then you can compose a new position (still pressed halfway) and when the composition is good, then press it further to capture the photo.
allisonsylvi, That's hard to answer until it is seen by the repair person, a reputable repair shop might be able to cannibalize another camera for the pop up flash parts pretty cheap and you just have to pay his hourly rate (the big variable). If the camera still functions otherwise and even the pop-up flash still works, you may want to go low-tech and hold it down with black electricians tape. You can turn off the flash so it won't want to pop up even in low light situations. If you use a flash attachment it will produce better results anyway. The D100 is a tough camera, lots of photojournalists were the first to embrace it for its durability out in the field. (metal body as opposed to plastic parts) randy320sgi
Generally, a Nikon AF body - lens needs something of contrast to focus on (i.e., the tux of a groom) and with a white wedding dress, the autofocus tends to go 'nuts.' You could pick a spot (a pew) to focus on and then turn AF off: during the walk-down-the-asle, just shoot when the person hits that spot. In a less-than-bright church, maybe your eyes and digital are not a prime match. You could return to a film camera -- the F100 does well in lower light.
