Is your photo "sharp", not too sure ?

Post an example here - the ONLY thing assessed is sharpness at the focus point

No editing on this one


PS moved this to pp help as you were asking for people to post pics which isnt' really suited to F-stop

did you tell me you focussed on the head ? even so, its not critically sharp imho

I can only assess the image in totality

hmm, looks to me, IMO that the focus point was the rock under the beetle?

Many thanks. This was an experiment in using a fast lens. Controlling the DOF is more finicky than I thought!

Taken with one of those "old" D200's and a cheap 3rd party lens.

How about this Marlo chook, is it sharp?

Jeremy

Top one (crop) is brilliant focus- no problem. Skin texture and colour show up so well - terrific.

Answer: Of course it is sharp - wonderfully sharp - I like sharp. But can't gauge the sharpness of the eye.

How's this? Just bought a new lens and only had a chance to take some quick test shots around the house.
No sharpening. The first just resized, the second - 100% crop upper right corner.

Bah! Some of the images you're calling sharp have enough digital sharpening applied to produce noticeable artefacts.

Slightly softer but more natural looking would be preferable.

Re: Pelican neck feathers

The image looks a bit soft to me - F-stop too small (?)

Both eyes sharp Jeremy.......... one on the fisherman cleaning his catch, the other on his pelican mates competing for the spoils....:D
