In a little be of preparation for the impending 8x10 landing at Hoof photo hq I'm going look at learning and practicing contact printing some of my 5x4 negs.
I have some photo paper left from a pinhole project, Ilford multigrade iv deluxe 5x7 and have a set of Ilford paper developer chemicals. So seeing as I have the stuff I don't at the moment want to spend too much more...
Reading up, basically I need a light source, a negative, paper, a sheet of glass and a stop watch.
The paper goes down on a flat surface with a negative on top. The glass is placed on top to keep negative and paper together as any gaps between them will distort the picture. On the couple of bits on the net I read about having a low wattage lamp 15w approx 3 feet away. Then its a little bit of experimentation as to exposure times.
I was thinking, with regards to clamping down the neg and glass, could an old picture frame work or does glass need to be special? Various people say it needs to be thick but that's to hold the negative down a frame with a board could clamp it. Also some people say frosted glass helps as it helps defuse the light.
Lighting wise, would I need use an old school filament bulb rated for 15w or would one of the newer 7w energy saving types be better (I'm aiming for a slower long exposure as i will be timing the switch myself!)
As for distance, is 3ft about right?
Comments welcome
