First Shot with my New DA35 Limited

All shots at 1/45 5.6

This is our little bowl of shells, sea glass and corral from around the world.

I don't know if it is the lens but when I went to sharpen the image I found myself using .3 pixels instead of my usual .5-.7. Could this be because the image was already pretty sharp or am I imagining things?

Thoughts and comments welcomed.

I see no difference in the resized images. The first one is perhaps even sharper and looks good.

Note that sharpening web resized images should be done *after* the resize and its main purpose is to counter the softening effect (which depends on the resize algorithm/parameters) of the resize itself. Minor unsharpness of the original is hard to judge on resized images anyway.

Your 100% crop does clearly benefit from the sharpening but the original looks ok to me.

Enjoy your new lens!

Sharpen after resize

I did not understand the resize/sharpen issue.

Can you post the best way to present a photo for critical inspection.

I have been:
Shooting RAW
Touch up exposure in LightRoom
Then moving to elements where I view at 100%
Then cut out my crop and past into a new document and save as JPEG
I go back to Lightroom and save the original RAW file as a JPEG and resize as part of the save.

Should I use JPEG for this or another format?
You say I should sharpen after resize?

Any hints on how to best post photos for critical review would be appreciated.

thanks,
joe

I disagree with tomtor - I can clearly see the improvement in the sharpened image.
As for the OP's question - maybe it's just this particular image, or your focus point that caused you to need more than usual. Would be useful to see a crop of your usual sharpening setting on this image.

All your steps are ok for a critical review of the results of a lens.

The suggestion of "sharpen after resize" is however not for lens tests, because resized images do show colors/contrast etc, but make it hard to judge sharpness.

The "sharpen after resize" rule is for publishing your artistic work as resized JPEGS.

When you just resize (eg combined with save) then your resulting images will appear a bit soft, even if the original JPEG image is ok. This softness is the result of the resizing itself.

So the last step "back to Lightroom and save the original RAW file as a JPEG and resize as part of the save" will not be ideal for publishing your work on the web. The better approach is to:

- resize in Lightroom,
- play with the sharpening options on the resulting smaller image until you get a nice crisp result (I assume this can be done in Lightroom and that you don't need PS for this, I don't use Lightroom)
- save the smaller image as JPEG without further processing

The OP needed LESS sharpening, not more...

I have the DA 35 f2.8 Macro Limited, and it's fast becoming my "standard" lens. The image quality's superb.
