![]() 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. So whether you’re a professional designer working on technical drawings, a fabric and craft hobbyist or a photographer, you’ll love our high quality light boxes and light tables for drawing or QC tasks.Spectral-sensitivity-curves 1428×1124 123 KBīasically, all this means that modern digital camera sensors will pick up more interference with the orange mask than photo paper would. And because they feature the latest low energy LED bulbs our light boxes have a lifespan of over 50,000 hours! This means that we’re able to create a sealed unit that is protected against dust and splashes and provides a hardwearing and truly multi-purpose unit. ![]() Our LED light boxes are available in all shapes and sizes and are the perfect choice for everything from large format displays and advertising to inspection and design work. The water resistant and sealed design of our BeamBox means that you won’t have to worry about spills when carrying out experiments or quality control checks. It’s not just photographers who’ll see the benefits of our BeamBox light boxes as they’re also perfect for scientists, researchers and technicians for conducting inspections and experiments. The integrated touch sensitive dimming switch offers step-less control ensuring you can get the light level you want. With an edge-to-edge illuminated work surface and a modern, minimalist design our light boxes let you see every detail of your work. Our BeamBox LED light boxes are used by amateur and professional artists, designers and illustrators and are a great way of improving your workflow.
