How to shoot sharp pictures
I have a Canon Rebel 2000. The first film I used on it was ISO 200, the pictures was acceptable. I change to ISO 400 looking for sharp pictures however, I found some Yellowish in all my indoors and outdoors pictures. How I can take sharp pictures?

Sharp pictures? 1. Use a tripod.
2. Use fine grained film
3. Shoot with your aperture around f5.6-f8 (generally speaking - it varies from lens to lens)
4. Don't stack a lot of filters on your lens
5. Use a lens hood ....anyone else care to add to the list?

Lens quality. The optical performance of a zoom will not match that of a single-focal-length lens unless you buy a pro caliber zoom lens with a pro price tag. The difference in resolution capability between the two can be pretty obvious even to the naked eye. If you can't use a tripod, try to increase your shutter speed. If shooting with a telephoto lens, another sharpness problem occurs on hot days because heat rises from the ground and distorts the air space. Good luck.

I second what Gilbert said about lenses. They're the most important part of my camera systems. Some additional thoughts: Film Speed:
Going from ISO 200 to ISO 400 in film speed increased graininess. Depending on what films you were using, this increase in grain could be significant. There are some horridly grainy ISO 400 films, and the most grainy are the cheapest consumer films. They're so grainy that it's visible at normal viewing distance in 4x6 prints. Yellowishness Indoors:
Applicable to indoor, but not outdoors. When shooting indoors with a flash, some of the light for an exposure comes from the flash. The rest comes from "ambient" light that's already there. When you doubled the film speed, you also decreased the amount of light required for an exposure by half. If the ambient lighting remains unchanged, the amount required from your flash goes down by more than half. If your ambient light is also from incandescent lamps, it's not daylight and does not have nearly as much blue content as daylight does. It's mostly red and yellow content and *will* make an available light photo (no flash) yellowish looking on daylight balanced film. Fluorescent lights give daylight film photos a greenish cast. With a fast daylight film and flash indoors you end up with "mixed" lighting which can pick up a yellowish cast from incandescent lamps if there's a lot of ambient light from them. Yellowishness Outdoors, Possibly Indoors too, and Other Problems:
I suggest trying a different lab to process and print your film. This may be most of the problem. A print is a photograph of your negative and its quality depends not only on the quality of the negative, but also the quality of the print enlarger and its operator. Many people don't know this, but the print machine operator makes decisions about how your prints should be color balanced and can easily make huge adjustments a print's color balance. If the operator doesn't know what he's doing, or doesn't care, you can end up with all sorts of problems. If the machine isn't maintained well, its optics can end up out of focus, its color balancing out of calibration and the sharpest, well balanced negative can end up the blurriest print with the ugliest colors. -- John
