    Default exposure question

    If i have a lamp of let's say 150W, and exposure time is 5 minutes, what happens if i use two lamps of 150W?
    Would exposure time then be around 2,5 minutes, or would it still be 5 minutes?

    Is it illegal to expose yourself in Belgium?

    I was wondering what the effects of leaving it to burn too long is?
    Or having too much sensitizer in the photo emultion.

    Thanks

    Waffles are okay. Pancakes are the way to go though. And no exposure time!

    too much exposure = can't wash out your image. have to clean it and re-coat the screen.

    too much sensitizer = never thought about it, but maybe it would expose a little quicker? i guess it's better than not enough sensitizer in the emulsion. what kind of emulsion are you using?

    Maybe that was my problem. One side of the image was really faint, and I had to scrub at the screen with my fingernail to get all the emultion out of it until it turned from blue to clear.

    I'm not using a home computer and I can't remember the name of the emultion. I think it's probably pretty standard stuff.

    I did actually make the mistake of not putting enough in (it's hard to tell in the dark), the emultion stayed blue instead of turning green. I had to clean the screen and start again, which was a hassle but worth the learning experience.

    Thanks for the info. Trial and error I guess.

    Does anyone have any advice for using a 500watt blub for burning the image? I left it for about 25 minutes. I'm not sure what effect that had on the end result.

    I've helped 'Yo Rodeo' screen a few times, in different steps, but two days ago I did my first screen by myself and want to get better and better at it.
