I want to do some testing where I need to expose by contact 4x5 negatives with a step tablet.
I have no enlarger and no timer because I intend to print digital. I would need a way to expose the negative to uniform light otherwise the density reading will be useless. Also the exposure time as to be such as to avoid reciprocity failure but the film I'll be using for this is suppose to be ok between 1/10 and 1000 secondes but I would like the method to do this applicable to less tolerant films.
I'm willing to spend a minimal amount of money for this, say less then a $100 much less if possible. If you have any suggestion I would appreciate greatly. Thanks
