The 'blad lenses are so much more "correct" and natural compared to all my Canon digital stuff, I really miss that look... one reason I got the Safari was to turn it (eventually) into a remote "studio" ala Irving Penn's "worlds in a small room" project...I want to rig up an extension to the Zip Dee and use canvas 'walls' to do location portraits...good luck shooting!

Rick,

Sounds like a dream come true.

Also like the work on your site. Well done, you have a real talent for the portrait!

Very nicely done. It is refreshing to see someone do something as well as you have. Bravo!

Thank you all for the kind remarks. Here is a final photo after we painted the underside of the overhead. I am working on an article based on this design to include detailed build and assembly instructions. Not sure where we will submit to but have to get the article written first.

From the responses, sounds like you could make some money selling these!

Nice work!

So they are very similar, at least in terms of what B&W film would see.

Hi again Royce,

Was admiring your work again today and have a question. How many automotive bulbs were yielding 7.66?

Thanks,

Beautiful fixture you made! I've always been better at making things work, than making them nice.

It is a good idea, mixing warm and cool white. The only drawback would be, if the two hues are spatially separated like in the picture, it will result in shadows with a strange chromatic fringe. Blending the two types across the whole fixture will help prevent this, but it is difficult to do with prefab strips.

I bought some very nice 10mm discrete LEDs on ebay from a hong kong seller. They include dropping resisitors for 12v applications, but I'm going to make mine in groups of 3 LEDs in series for each dropping resistor. I figure two cool whites and one warm per group will look good. The trouble is, LEDs are so directional it is hard to blend the light. Being inside a bezeled fixture helps. Make sure all surfaces inside the fixture are painted flat white, this will help.

I don't have the URL handy, but google for "led resistor calculator" if you're designing something.

Something I'm doing in one of my other (SOB) trailers is adding a bank of red LEDs to the fixtures. This is to preserve night vision, for stargazers and hunters. On a total resto, you might consider adding at least one extra wire to each fixture, for a single on-off point for the red.

Thanks,

Vaughan,

That would be three of the 12V lamps with the factory diffuser in place.

That is a great idea! Save carrying a separate red light.

Thanks Royce,

The lights in the Trade Wind have four in them. Now I know what to compare to.

Was reviewing this thread and remembered something. Our building was paid for with a grant from the Donald W. Reynolds Foundation, and there is a bronze bust of Mr. Reynolds near the front elevators. The pupils are recessed and the bust is lit with four small low voltage spots in two different colors resulting in blue eyes on the bronze. Subtle, but still an intelligent use of the phenomenon you are describing.
