The batteries go round the edge of the unit – I’m using ordinary NiMh rechargeable cells (not supplied). There is a 5V input at the side too, although I didn’t have the right voltage power supply at hand to test it.
I’ve exposed this image to emphasise the light fall off – it’s not so obvious in normal use, but you should be aware of it.
Glass shows the reflection the most, although the shiny ceramic below picks up the ring shape.
The wooden die has a slight gloss to it from wear, but is giving a smooth look, with the sides not too dark. Here’s an animated GIF file showing the image processed straight, using Adobe Camera Raw, and when using the DNG profile.
The difference is quite clear (note though that this is a GIF image so only intended to give a feel for the change). I’ve seen far worse with artificial lighting, but it’s enough that I’d definitely make a DNG profile for improved colour accuracy if I’m just using the R60. Great for flat shadowless lighting if you’re doing cataloging work, and don’t want the peak intensity of a flash unit which might damage delicate specimens.
