Are you shooting in raw format? It seems like the camera converted this to jpeg which is never a good idea.

It seems too saturated and vibrant more than anything.

Now that I think about it, I've got a probably +2 watt RGB-led board with a programmable controller on it salvaged from one of those programmable LED light bulbs. If I can reverse the IR protocol for it or identify the microcontroller on the board for reprogramming, it and a battery pack might be just the ticket. It could even be that the original remote can be retained.
Otherwise, I have a bunch of microcontrollers sitting around and could scavenge the high wattage LEDs from something. Let me know if any of you want to pursue that.

We cannot upload RAW files here, I shoot in RAW then edit the image and convert it to jpeg, I suspect vjp does the same.

Yes, I make them, I use two rectangles of thin but rigid plastic(waterproof) taped together in the middle so they can fold and stand like a pyramid, I crinkle some aluminium(aluminum) foil then straighten it out and glue it to one side of the plastic, the crinkled foil diffuses the reflected light, I have two of these reflectors and usually position them on either side of the subject, I look through the eyepiece and change the angle of the reflectors until the light looks good.
The use of these reflectors with natural light plus the flash set at it's lowest setting generally gives me the best results, I usually have to take three or four images before I get the desired result but occasionally I get it first time.
I seem to get my best shots around mid morning, between 9am and 11am and usually the light is coming from behind the subject.

I have never taken photo's of mushrooms.
I was speaking from experiences in other fields. Light is light, it works in the same way regardless of the subject. Mushrooms will just be a bit more challenging because they are very small.
I make a living with architectural and interior photography as well as assisting addvertisement and still life photographers on commercial jobs for clients such as vodafone, esquire, range rover, chocomel, etc.

The most fun way to learn about lighting (apart from experimenting) is probably this blog:

I use a König ring light KN-RL60 (5500~6000 k temperature). It has adjustable power to the LED:s. http://pictures.content4us.com/products_high_res/KN-RL60_2.JPG Cheap, but good to have when photographing mushrooms in dark conditions. No need to have photos ruined by extreme ISO or blur due to the longer shutter time.
I also use it when I´m hunting mushrooms at night, it's great for this purpose.

You know what; I'm just going to get started on it anyway. I'll probably not get it right so I can see about the color temperature stuff after I make the hardware and get started on the firmware.

Pretty good on my monitor. Maybe just a tad washed out. I'm used to seeing those slugs a bit darker but perhaps he's just a light one. I love their little skirts.

Appreciate the feedback. Are the colors on this one a little better? Increased the yellow highlights a little and increased the saturation a little.

Yeh, that one looks a bit better to me. But I don't bother with monitor calibration or any of that, so don't take it as gospel. ;-)

I am about to buy a calibration unit. I might just give up and blow my camera up. The picture looks weird the more i look at it.

I'm a relic from those days where people still used film and photographers were magicians. I've never liked using flashes...for obvious reasons, so I manually override everything and pretend I'm using film.
I disagree about the color balance thing being about your camera doing a crappy job at properly recording the color information (someone said that, right?)...it could be a number of things, I've found the likely culprits are the color of your flash and the fact that things are a lot more reflective than we give them credit for. (Do people still use color filters on their lenses? Or is that all post production now?)
Something I do with directional flashes is bounce the light off of bounce cards and tie lens cleaner tissue over top of the flash with a rubber band to diffuse the light. Then again, I just screw around with f-stops and shutter speed and avoid them altogether if I can. Seriously though, you really only have to worry about exposure--getting the color and contrast right has pretty much always been during the editing process, even back in the dark ages when people used to print and develop their photos on photo paper with an enlarger.  That slug making out with that shroom is sexy. I would totally do the same. Try putting some blue/violet in the shadows and increase the orange in the midtones and yellow in the highlights. You're using photoshop, right?
