Sarcophagia Carnaria - head shot

Post by AndrewC »

Image

Flesh Fly at about 4x

El-Nikkor 50/2.8 @ 5.6
Stack:100x51um, ZS PMax
Lighting: SB-R200 x2

I like the pose of this one, has a slightly feline air to it ?

The SB-R200 flashes give quite good diffused lighting but on shiny body armour there is too much specular reflection, I'll need to move up to a more diffused source like a table tennis ball.

Question: has anyone else noticed that uploaded images seem to get softened ? If I compare the identical image uploaded to PM, and that on my own website I can see a noticeable difference in sharpness.

Your eyes are deceiving you. If you download, save, and binary compare the image files from your own website and from photomacrography.net (http://www.photomacrography.net/forum/u ... ria2_2.jpg), you will find that they are bit-for-bit identical. Or you can layer the two images in Photoshop, set the mode of the top layer to Difference, and see the same thing visually.

I don't know for sure what is causing the perception you report. It sometimes results from differences in perceived contrast, which is affected by the color and brightness of the surrounding page.

The current photomacrography.net upload procedure does not alter images unless they exceed the posting limits of 800 pixels per side, 200 KB per file. If either of those limits gets exceeded, then the upload procedure resizes and/or recompresses the file to make it fit the limits. In that case all bets are off regarding quality.
