Hypodermic needle used for subcutaneous injection of Insulin. Needle diameter is 0.25mm. Lens combination was a Tamron 90mm SP Macro, with 57mm of OM type extension tubes and a MF-1. I tried using an EX25 with the 18-180, but manual focus is very coggy when seen with the E30 in magnify mode. I moved the camera instead, but the picture was still better with the Tamron.

Don't like it too much

Sorry to be direct, but this picture doesn't have too much interest besides the technical difficulty of shooting a small target with macro.

The background is plenty of chroma noise, and the composition is not appealing.

On the technical side, the magnification is not bad.

Hi Jes, Thanks for your comments for this one, and for the trees. This photo came about from seeing how much magnification I could get with the equipment I had. The noise is due to absolute minimum noise reduction to preserve detail, and the 'straight up' approach seemed to maximise agression! Magnification is around 50 times, depending on your screen.

Magnification

>Magnification is around 50 times, depending on your screen.

Really?. It's much higher than I thought at first...

I would have put the needle diagonally across the image, and some noise reduction via Noise Ninja would do little harm on the details, removing mainly the chroma noise in the background.

I've taken the freedom of modifying it as I think it could be done:

One improvement could be to place some object nearby the needle to get an idea of the proportions.

Knd regards,

Jes.

The object was to show as much detail as possible. I had a go at reducing noise using the digital noise tool in Paint Shop Pro 9, but any thing I did reduced detail beyond what I wanted. I'll have a go at showing it with something to compare proportions - Mike
