Since I will have my first PINHOLE experience next weekend I thought the "beginners" was the best place to ask my simple question:
how do you figure out the correct exposure time when you are dealing with minutes and not fractions of seconds??? How do you cope with the reciprocity failure??? Is there ANY rule to follow (I use HP5)???
ANY advice is greatly appreciated.-
Cheers, Paolo
Go to the "pinhole resource" website they have links to some great exposure calculators. If you do a search on this site you should be able to find more than one reciprocity failure chart for HP5 is not i know there is one on the AZO Forum. Have Fun
There's a freeware mini program with lots of exposure info. It's called Pinhole Designer and I'm not nerd enough to link you to it. You'll find an exposure chart for HP5 as I recall. Also ask questions on the f295 website.
Thank you for your help. That pinhole Designer Freeware is just GREAT.
Grazie
Now don't forget that Worldwide Pinhole Photography Day is coming up!
