![]() ![]() I have to say it is a huge upgrade from my previous LED light (a cheapo tracing tablet). I read about this new LED backlight on Reddit, and I ordered one. The MR16 utilizes the ENTIRE interior reflector with the coating. Reason? In the large PAR38 / PAR series, only the bulb is coated with the patented vapor deposited film. Be advised however that the larger PAR38 Solux does NOT have the same performance and the CRI drops down to low 90s, R9 deep red goes down to mid 50s with the larger sources. Look at the Solux 4700K - darn near perfect. Previous chart of the iphone 7 was quite ragged. The bottom chart is a sampling of 99 different colors and their accuracy. Glance over the right hand panels and you’ll find very little deviation from ideal. There aren’t any “hot blue” ramps like those found in the Profoto, Alien Bee or other flash units, nor are there any “blue pump” peaks like those found in 99% of the LEDs on the market. Take a look at the spectral distribution in the upper left panel, a D50 match. Easily surpasses the SORAA LED in all regards. With regards to a constant “hot light”, the Solux 4700K is THE reference source to beat. GE Reveal or Chromalux tungsten light bulb with a CTB gel or an 80a filter.Other options worth exploring (not LED panel) Any modern Samsung Galaxy/Galaxy Note s7, s8, s9, pixel 3, etcĪrtograph light pads (unlisted CRI, although reportedly ~80 CRI).It is also a more “collimated” source of light, meaning it will produce sharper results than diffuse light sources. While the reported CRI is not high, it has spectral sensitivity curves more similar to film paper, resulting in less color interference from the orange mask. iPhone or iPad, especially newer models with OLED (must elevate film off surface!).Kaiser Slimlite Plano (CRI = 95, very even).Negative Supply - Basic Light and Light Source Pro (95 and 99 CRI).Skier Sunray Copy Box II - 97 CRI light that is bright and even, and includes film holders for a variety of sizes that keep film flat and elevated off the surface.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.
