Red Flour Beetle

I was passed this tiny beetle to ID. Several were found in a medical factory clean room causing problem.
It turned out to be a Red flour beetle Tribolium castaneum.

Took this photo using a ping-pong ball defuser. Not too sure of the results.

Looks pretty good to me! What aspect of the results are you not too sure about?

Wow, I like the shape of the head and eyes. Good work.

No stacking artefacts obvious at this size that I can see. Perhaps post a 100% crop if there's a particular bit you're not happy with?

I like the colour, and the exposure is good..

Hmm... I think the lighting is a bit too even and adding the grey background, it makes the image look kinda flat. Other than that, it looks pretty darn good.

I have a question though... Sometime I see |______1mm_______| in an image here, how do you guys find out the exact scale?

I use a Meiji EMZ-5TR scope for my mineral photography. The zoom range is from .7 to 4.5. At each of the numbered zoom increments I have determined how many millimeters the horizontal field of is. I place a millimeter scale on the stage, go to live view and record the FOV for each setting. In Photoshop, I add a scale bar that represents 1/4 of the FOV.

Thanks for the explanation Doug! I'll give it a go later tonight.

Very nice image morgan. The eye is most interesting. Walt
