Thank you for your information Danny, perhaps they also use a macro lens, I suppose it is the choice of the individual staff there. One moth woman told me she uses a zoom when she uses the light box. Anyway, I was pleased with my macro shots and I must say Adam's image is excellent.

Here's my homemade lightbox: Yes, it's a cardboard box with a hole in the middle It sits on a sheet of frosted glass, you can see the raised glass scale inside, below the plasticine that holds the specimen in place. The lights are LEDs as you can see in the next photo. Adam. I guess the frosted side is up so there is no reflection from the LED lights. Adam I hope you could show me this setup in person as your picture looks amazing even though is taken only with cell phone camera. Paul

This is my copy stand and lightbox set-up; I've had this for about 20 years now and it still works fine. I bought the copy stand off eBay and had a local metalworker knock up the lightbox for me. The bulb is a daylight bulb that is about as close as you can get to replicating natural light, they were expensive and I had to import them from the States, I bought the ballast from a local electrical shop. It wasn't cheap as it cost me about £300-400 for everything, but I use it quite a lot and I'm only on my second bulb in 20 years. It does make a huge difference to the colour quality given the right lens.

I used to have a similar ring fluorescent bulb (but a cheapo daylight one) taped under the hole in my cardboard box, but I found the strobe effect was much more of a problem, hence I switched to LEDs.
Have you ever had strobe problems with your bulb (probably not I guess)?
Adam.

I thought that would be the case, otherwise you would have said so.
The moral of this story is don't use ordinary daylight ring fluorescent tubes if you want good results. That's why I changed to LEDs, there was no chance of getting expensive bulbs from the USA if I actually knew they existed.

As promised . Here is the light box I used yesterday in the museum. The light is provided by a glass ring at the top of the box, as shown by Bob.
