literally displays a screen filled with one color, for scanning negatives or other uses. Like a flashlight, or video light.
Uses OpenGL. Why? CV-driven development.
-
Y, B, A - increase amount of red, green or blue.
-
R + Y, B, A - decrease amount of red, green, blue.
-
X - increase brightness.
-
R + X - decrease brightness.
-
Up, Down, Left, Right - presets.
-
Held U/D/L/R - preset overwrite with current setting.
Presets are written to a text file /switch/lighttable/presets.ini, so you can modify it as you like in your favorite text editor (the biggest problem - no native vim port on Switch). In case such a file does not exist, it will be filled with default values:
-
Up, left and right is brightest, whitest;
-
Down is least bright, black, to save power.
-
+ - toggle display of parameters.
-
- - exit
- implement everything listed here
- add 35mm/645/6x6/6x7/6x9 borders for aligning negatives (of course, created as OpenGL vertices-objects thingeys - sorry, I'm really bad with computer graphics)
- absolutely retarded, as the screen has horrible PPI and is an LCD and not an OLED - a gallery app that displays >negative< of the given images, and cycles through 6x6/6x9/24x36mm formats so you can slide your switch in the film carrier of your enlarger and print digital pictures.
