This is what flickr does for size 1024


and this is what I got fiddling in PS


I'm sure better is possible, to some extent it's a matter of taste. The specialist sharpening plug-ins can do well.

This is f/8. For this size of reproduction, it's not possible to see all the detail in the original image, which means you'd be better with a smaller aperture, more DOF, and more diffraction which wouldn't show.


Looking at Rik's DOF Two Ways
I plugged in Magn = 0.2 ( a guess)
and "sensor width" 1024 pixels
and C of C = 2 pixels (a suggestion)
It says the aperture is right, at about f/33.

I would like to thank the patience and the help from everyone, and sorry for being such noob Smile We were on a night herp trip last night and yea, found the problem. Some people might be able to shoot perfect macro pictures hand held, I am clearly not one of them. The camera (specially close-up) shakes as a 90-year old man who forgot to take his parkinson medications. And I still donĀ“t have a flash on! Smile

Guess it is individual for everyone. Thanks again for your amazing help everyone in getting this far, I will update this thread once I have my new tripod and flash unit.

So I just received my Yongnuo YN-565EX speedlite and my flash diffuser ($1 plus delivery haha). Will have to go out and test it some day, but it looks really promising! Smile

Your next important purchase might be a cheap flash bracket to get the diffuser much nearer the subject. For testing of course you can just hold it.

You should be able to use a Commander (wireless) trigger mode, but if you have to have the on-camera flash working to do it, that one might need shielding so its light doesn't hit the subject directly. Black tape may be ok if it lets enough IR through.

I just wanted to check back to this and see what has happened since May. It has been a couple of months and I can see that I am getting there. I still need some gear and I think I will change my D3200 to a D7200 as it is not "enough" anymore in terms of quality. Also I bought a tripod which really helps in my work.

Contradictory to that here is a hand held shot of a bug taken 2 weeks ago, no editing done at all.

(For some reason I am once again unable to upload the image, so I will try and embed it...)




Edit AdminCR - picture displayed was oversize, so I have replaced it with a 1024 version which links to the Flickr page.
