finally got all materials needed to test the LED lights - my first wet plates ever
two lights from 200 cm placed next to camera lens to get even illumination
1st light : 24*48 5630 LED panels (cold white)
2nd light : 4 * 90W hybrid aquarium LEDs
2nd light is about 5 times brighter than 1st in blue portion - measured with arduino + tsl235r + blue filter
indicated exposure with sverdlovsk 4 spot meter at ISO3 against grey card : 1 second @ f8
raw frequency from tsl235r + blue filter placed in the middle of the scene : 34500 Hz
actual exposure : 2 seconds @ f11
materials and process: 9x12 black aluminium, OWH (3 weeks old), MD-4 developer, developing time : 15~20s, fixer : fomafix with water (1:4), without varnish, scanned with v500
this is my 2nd wet plate attempt (first plate was for the test strip) and these lights seem promising for wet plates (especially the hybrid LEDs)
