It seems as though you've been good busy though? The website sounds like it's had a big jump in demand! You can see the quality of paint in the BD's but I'm glad you posted on this; it does make a difference! I'm keen for the 22" BD, from what I've seen, it's fantastic. Keep up the great work!

After 7 months of owning the silver beauty dish (16" from ebay) I was tired of having too harsh/contrasty of a light and decided to paint my beauty dish white. I used a flat white color paint that I had in the garage and painted the beauty dish and the back side of the deflector. While the color temperature warmed up about 400 degrees (kelvin was at 5600 before and is now 5200) the quality of the light coming from the ebay 16" silver beauty dish was on par with what I had expected of a beauty dish: soft but still punchy light. As it stood before, the 16" silver beauty dish was more of a reflector than anything else which could have been replicated with a 7" reflector from 8 feet away even though a beauty dish is most effective at distances 5 feet and closer.

So was it worth painting the beauty dish? ABSOLUTELY!


Before: 5600 kelvins with a slight red tint

After: the deflector was painted white on the inside to spread the light but the front remained untouched.

5200 kelvin is actually "colder" than 5600..It doesn't make sense to me that a silver beauty dish would create a warmer tone than a white painted dish, but maybe your dish is special? No idea. There are other factors that could influence how your color temperature comes out - is your strobe able to consistently output the same color temp time and time again, in addition to the same amount of light from pop to pop? Not all strobes out there are capable of that, so that's something to bear in mind. Ambient light can also play a factor, just saying I'm not sure I buy that your white painted dish is outputting colder light than a silver one.

I'm actually not sure why the temperature became "cooler" but i had to compensate by lowering the kelvin in the 5d2. Usually when you are shooting in tungsten lighting the kelvin is set to 2800 vs normal florescent light of 5500. Tungsten is not "cooler" then florescent light.

just trying to explain.

5600K is "colder"--by which in color terms we mean bluer--than 5200K. It does not surprise me in the least that the paint you found around the house has a slight warm tone. Most white paints are more likely warmer (yellower) than cooler. You would have to use something with a name specifically like "arctic white" to find one on the cooler (bluer) side.

Did you paint the backside of the center reflector too? Wouldn't that also impact the light?
