Some Overall Photo/camera Help

Sun Jul 27, 2003 1:29 pm

Ok I have a few questions to ask to anyone who knows. I have been taking pictures for a while, and lately I have been getting more and more serious about it. Excuse my questions if they are very elementary.

1. What is ISO mean? (ex: ISO 100) I have a Cannon EOS and have seen photographers mention ISO in their comments. I saw there was an ISO label on the switch, but I could not take pictures on that setting.

2. On my EOS, what setting should I use to take pictures with? (of planes, generally moving) I saw a "flower, mountain, and a runner" labels on there.

3. I have a 300mm lense I used most of the time. I noticed that my pictures get grainy when I shoot them using the full zoom. (Not when I take the pictures, but post-development) Any way to fix this?

Guys, thanks a lot in advance. Any help would be GREATLY appreciated.

ISO (also known as ASA) is the "speed" of the film. Basically it tells you how sensitive to light the film is. The higher the # the more sensitive to light it is. Since you want to shoot airplanes in bright sunlight you want to stick with a lower speed film like 100 (if shooting prints. If you shoot slides you can go lower like K-64.)

Start off with using the "auto" function on your camera or try to play with the other settings that allow you to set either shutter speed, f stop or combination of the two.

Grain is something that is related to film speed. The higher the ISO and the more sensitive to light the larger the grain. (VERY simple explanation here...) I would guess you are using a higher speed film like 400.

Your best bet is to go take a photo course or at the least pick up a book or two on basic photography. Learn the relationships between speed and f stop, focal lengths, depth of field, etc....Learning the basics will save you lots of headaches later. (I found the National Geographic photographers field guide a very nice book. Lots of good info in it in simple language.)

Good luck, Tony

Switch it to the picture of the little plane "thingy", unless of course you are taking pictures of flowers, mountains, or runners.... then switch to one of those!
gotta love Canon's little picture things... [j/k]

I was just doing a little Canon teasing Ryan. The Nikons I have used don't have those little pictures on them. I recomend trying them all and see witch works best for the type of pictures/conditions you shoot under.

Thanks again Jeff.
So let me rephrase this..Is this correct?
Use a lower ISO for sunny conditions, use a higher ISO for darker conditions..

What film does anyone recommend for real good quality?

Thanks again guys, I will give you the before and after pics. I keep learning and I keep getting better.

1) ISO means the sensitivity to light. Higher ISO is more sensitive and will allow faster shutterspeeds in lower light.
Most of us use ISO100 film almost exclusively (or slower).
THE best film out there is IMO Fuji Velvia 50, but you might want to stay away from that until you get more practice. Start with Fuji Reala (which is a printfilm, easier to use than slidefilm) and switch to Fuji Provia when you get practice in getting correct exposure.

2) As Jeff said, experiment. I suggest you study the manual to see what each setting is suggested for and decide on the most suitable one based on that. You will over time want more manual control than those program modes allow...

3) When you get grain at long focal length that means your pictures are underexposed. If it persists you might want to have your camera and lens checked out.
