Red Flour Beetle

Post by morgan »

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?

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.
