Any have experience using a lighting system similar to this? http://www.amazon.com/gp/product/B0054EI7BG/ref=as_li_ss_tl?ie=UTF8&tag=theonlinephot-20&linkCode=as2&camp=1789&creative=390957&creativeASIN=B0054EI7BG
If you do, how do you think it would translate over to mushroom photography?
I really like my macro ring light, but it's nearly impossible to get perfect white balance due to the weird color temperatures of LED lighting. I put a orange diffuser on and that helps take away the weird blue hues, but it's still not what i'm looking for.
I think having adjustable color temperature, power control, and constant light might help. What do you guys think?

You're a photographer right?
Use a flash.

I've bought 3-4 different flashes for mushroom photography and none of them produce the results i'm looking for.

Why not? What are you looking for? Can you show me expamples, I should be able to tell you how it's achieved.

Flash does not make miracles nor does corupt colors by default.
It is more the problem of color processing in camera.
Forinstance this was taken with nikon R1C1 kit. The yellow of gills should be more intense.
For that prob I go to camera 'set picture control', change from neutral to standard, And I get more intense colors. To intense for sure, one day I will study that prob. into depth.
For 99.9 % of cases camera neutral & R1C1 works without problem, in rest cases blue & violet problems, strenght of color poblem, not existing color (i.e. they are there in nature but not on image), etc.
Otherwise if you are going to buy something, the other day I seen on net thing that looks like ring flash and works optionaly as flash or as light. That could be very good.
R1C1 (instead of controler on top of camera I have SB 800) --> the good thing is that you can remove one or two of those small flashes and produce lighht from under mushromm, I have 'big flash' on camera & optionaly move small flashes around
see example, small flash to the left from shroom, big one direct on it, a bit owerexposed, but still magical: http://agrozoo.net/jsp/Galery_one_image.jsp?id_galery_obfuscated=2a65a504d01d45f8987328cd36b3cb0f

That really looks pretty cool, I think you should get one. Kind of odd to have such a big thing attached to your camera though, maybe it should go off to the side and have a reflector on the other side to provide better illumination?
If you get it and it works well I will totally buy one.
Interesting how the color temperature is adjustable, I wonder how that works? And how does that interface with the color temperature white balance on your camera? In theory it should interface really well....

I can't really show you examples since none of my photos come out how i want them too.

I agree. But i also think that for mushroom photography it's almost impossible to get a correct color balance without post processing.

My plan was to create a homemade stand. The majority of the light would be used to illuminate the gills/stem and the rest would be reflected off of a umbrella that has reflectors on the underside of it. The light would then be reflected on to the caps.
Quote:

I think it works by combining two different color temperatures of LED lights. I think it should interface well, but it will take some practice to narrow down the correct color temperature with default white balance settings on my camera. My camera can't change color temperature in-camera like many cameras can.

I fear you will be disappointed and still unable to get what you want.
Find pictures from other photographers that show aspects of the effects you are looking for and research how they are shot. Once you understand lighting you can start making it your own.
Also, do keep in mind that a lot is done in post. Color correction is a big part of that. This was even the case in analog times. Darkroom color corrections were a very important skill.
It's not only about getting the color balance right. (Which should be a lot easier with flash as you are overpowering the daylight and don't have to deal with different temperatures of light!).
There will also be hues caused by reflection. If something pale is close to something colorful, the light reflecting from the colored surface casts a hue on the pale object close to it. This is pretty much unavoidable (direction of light makes a difference though) and almost always needs to be dealt with in post.
If you want the colors to be "realistic" use one color temperature of light (daylight is one so if you use the led you're mixing in a second which will make things complicated - that's why I advised flash). Make a small grey card and use that for setting the color balance. This will be your best starting point. From there, use post.
If you want to freak the colors, then you have ordered a great lamp.
Good luck, even though I am skeptical I do hope it will work for you!

get some reflectors, if you are worried about color balance, use natural light and diffuse that with umbrellas, I think any artificial light setup is not what you are looking for, set the white balance to custom on the camera and adjust, or on your computer. Either way, cant wait to see what you come up with

If you over power daylight with flash than you will have harsh dark shadows and unrealistic colors. I am looking for a fill light - to lighten up the gills and stem and bring out some color. Flash/lighting should be used for color not exposure.

I use a umbrella and reflectors - still doesn't produce what i'm looking for.

I guess i havent seen enough of your pics to know what you are talking about..

Would be fun to build one of these from scratch. The leds are super cheap on ebay and I am thinking a box of chocolates would make a good enclosure. I would have Joust calculate the resistor values since he is super good at math. Should not take many leds for a little fill light since I usually use long exposures. For the color control I could repurpose an old joystick since they are basically dual potentiometers.
Any ideas for a durable DIY diffuser?

Hey, i did circuits for a year  Already sounds badass.
Diffuser? I would go with frosted glass, bet that would be interesting, bet there would be a lot of vectored light haha

Depends on the type of flash. You can bounce the flash off of something, use umbrella's, ring flash. There is always a way.

Depends on the shutter speed you're using. If you use the flash synchronisation speed you will not be registering any of the daylight. It's all flash then.
Quote:

You probably will once you start using it. You are going to mix light of different temperatures which will make it hard to get any color right.
The easyness of possibilities would be (from easiest to hardest):
- Bouncing daylight - Flash only - Continuous lighting during the night. - Colour filtered flash mixed with daylight as a fill - Continuous lighting during the day.

Here is a example of the weird colors i get from my led macro ring flash. It is extremely annoying.

Quote:

With that light you can change the color temperature of the light. That way you can change the temperature to match the environment your shooting in. Most flashes and LED macro ring flashes don't let you change temperature and your stuck with a unnatural looking blue hue.

Hi vjp, I get those unnatural looking blue hues if I use no flash, reflectors, natural light and long exposures, especially under trees at midday, what I have found works well is to use the same technique but use the flash set to the lowest possible setting, sometimes I also hold a white sheet of paper in front of the flash to diffuse the light a bit.
I usually leave the white balance set to auto but you can try the shade setting or do a preset white balance with a grey or white card.
Learning how light reflects off different coloured objects has helped me greatly, for example, if you have a red surface most of the hues other than red become absorbed into the object so the light being reflected mainly looks red, if the object is blue most of the hues other than blue become absorbed and the light being reflected looks blue, when doing long exposures with very little or no flash be aware of the colours of your clothing especially if the sun is behind your subject and you are standing behind your camera, sometimes I have to set up my shot then walk to the side and use my remote shutter release.
I very rarely get the results I would like to get and just have to make do with what I end up with.
