A sectioned ammonite fossil; my first attempt at a proper photo with the 100mm f/2.8L macro. A beautiful lens, very well built, and optically excellent. I definitely need more practice to get used to it.
In this shot depth of field was a tradeoff against critical sharpness; I was shooting on a tripod with flash, so I wasn't limited in my choice of aperture. However, the majority of the subject matter was very close to the plane of focus, and I began to see losses in sharpness due to diffraction as soon as f/11 and smaller, so i chose to limit myself to that aperture - despite the loss of depth of field leading the image to be less sharp along the left edge due to the subject's surface curvature.
Editing: crop, cloning of sensor dust, tidying up the corners, and removing stray dust on the subject, curves to emphasise the blues in the shadows and reds in the midtones, resize and sharpen. |

| Very nice shot. I only have the Canon 60mm macro and love it. I would love the 100mm macro. Great job. |

Hello from the critique club
An interesting image that contributes well to the challenge
Another gem Eugene! A beautifully detailed image very well executed it very competently epitomises the essence of the challenge. You really are being very critical to make an observation of the very slight loss of focus detail on the left of the frame it really is so minimal as to have little or no impact on the end result. If there is anything to criticise I would suggest that the whites in the lower part of the frame are perhaps just a tad close to the limit? The colour and detail is excellent and well rewarded with your score and placement, well done Eugene. |
