Used to print the Photographs from 
Developed Film. Requires paper and dyes for every print.
Lightroom needs light to function. Light level above the block should be 12 or larger.
Chromatic Process:
Tinted Glass placed on top of Lightroom will make it Refracted, which unlocks Chromatic Process.
When toggled on (using the button on the left side), printing a frame will only print single channel at a time.
Doing this will produce a Chromatic Sheet with red channel printed. Use the sheet as a paper to print rest of the channels.
Channel consumes dyes that will make it's color when combined:
• Red: Magenta + Yellow
• Green: Cyan + Yellow
• Blue: Cyan + Magenta
When last channel is printed (blue), Chromatic Sheet will be converted to a regular Photograph.
Chromatic Sheet always receives channels in order: red -> green -> blue, regardless of the frame being printed.
Frames taken with R/G/B filter will have the channel shown in tooltip. This is only for you to help you choose correct frame for a proper result.
Redstone:
- When the Lightroom block receives a redstone pulse, it will start printing selected frame.
- After printing finishes - next frame will become selected.
- After printing the last frame, film will be ejected through the front. (this can be prevented by blocking the front side with a non-transparent block)
- This allows you to fully automate printing of Photographs.
