I’ll let members of the community jump in, but here are my personal observations based on my own experiments and files users have sent me: If you prefer the “softness” of a traditional fine-art print, go for a more diffused light source.If you like the sharpness and detail you see in drum scanners or dedicated film scanner (like Nikon Coolscans), try to get a more collimated light source.Which is better? Well, it’s really a matter of opinion and the debate has been going on for a while (in a darkroom setting, you can choose between using a condenser head (for collimated light) or a diffusion head.) Collimated light produces more contrast in scans.Collimated light produces sharper looking scans (whereas diffuse light will produce softer scans).To the naked eye, it appeared to be even lighting, but by taking a photo the led table directly (and then added contrast to approximate the contrast during a negative conversion process), you can see it is terribly uneven!Ĭollimated-vs-diffused-light-rays 1142×562 55.5 KBĬollimated light has two effects when DSLR scanning a film negative: Here’s a look at a Portra-Trace LED light table that was giving a users poor results. In my experience, it is very difficult to get perfectly even illumination if you are not using a professional LED light table solution (for example, a home-built led table, flash setup, old tungsten light table, etc)Įven pre-built setups can have some issues… Using a Kaiser Slimlite Plano, I’ve never had any issues with even illumination, and the results are the same every time. Also, there are things you can do in your set up to help with this. You want Even Illumination and Predictable Results I haven’t seen too much written about this outside the private Negative Lab Pro users facebook group, but examples of seen are extremely compelling.ģ. The ideal solution to this is to have a light source that produces distinct, narrow bands of red, green and blue light, that are in a similar range to photo paper spectral sensitivity.
