Have you already taken pictures with the pinhole camera!? A couple of your questions can be easily answered after you do!. These are homework questions, and you won't learn if you have others giving you the answers!. I will help with the first one, though!. A pinhole is a tiny aperture, and smaller apertures need longer shutter speeds for the proper exposure!. Look up exposure and film on the internet and learn!



Wow, and I get the thumb down!? LOL!Www@QuestionHome@Com

Hey, good luck with that!. You will be much smarter when you "learn" all of this on your own!.

Well, so much for you learning it on your own!. I guess fhotoace couldn't resist answering a question he could get mostly right!. Now both of you will have an 8th grade education!. Well, maybe you - fhotoace still needs to figure out question 3!. I would have thought Ken Rockwell would know that much!.

Oops! Looked again!. Only 50% for answer 2!. And to think, you could have made it up in easy extra credit on answers 4 and 5!.

There, have a thumbs up Terisu!.Www@QuestionHome@Com

1) depending upon the film speed, there is an optimal amount of light necessary to properly expose the film!. Since your pin hole's aperture is very small (f/stops can be like f/128 or smaller) the length of time necessary to exposed the film is long!.

2) As with all cameras the image on the negative is upside down!. Just look through the back of a view camera!.

3) There is no explanation necessary !.!. this is the way light behaves!.

4) all cameras produce negatives when using film (unless you are using transparency film)!.

5) the quality of the images are effected by camera movement and the precision of the hole you are using as your pin hole!.Www@QuestionHome@Com
