Re: Another questionable eBay listing

I don't know the sellers actual motivation. But I think this strategy could make an innocent buyer believe that since three different shops demand almost the same price it must reflect the generel accepted market value of the actual item. Of course this strategy would only work for legendary items r...

Re: Why aren't flies blinded by the sun?

Very intersting question and answers. I just want to add, that while we are used to enlarge everything with our wonderfull equipment we often forget the important factor of scaling in physics. Collecting the light from the sun through our own contracted eye pupil with a diameter of, let us say 2 mm,...

Re: Nursery Web Spider (Pisaura mirabilis)

Guido, don't worry about asking. Sorry for answering so late but I have been away from computer for 12 days. My camera, Olympus OM-D5 mk II, when set to focus bracketing takes a fast row of single pictures (JPG or Raw), around 10 frames per second while changing the focus a tiny bit between each cap...

Re: Nursery Web Spider (Pisaura mirabilis)

Thanks for your comment, Dalantech! With drifting clouds the light was changing fast. Diffusion is certainly a very good idea in harsh light. I always carry a piece of white diffusion plastic in my photo bag for use in sun light. Unfortunately I am no longer able to hold it perfect steady with one h...

Re: Nursery Web Spider (Pisaura mirabilis)

Thanks Guido! I used in-camera focus-bracketing and made the stack afterwards with Zerene Stacker. Although I could not see any movements during the bracketing, some of the spines on the legs moved a little. I had to do some retouching to remove "double spines", an easy task in Zerene. In fact I mad...

Nursery Web Spider (Pisaura mirabilis)

The mother guards her offspring seen behind the web in lower left corner. The lady jumped into invisibility when I arrived with the photo gear. She had already lost one leg. I had to wait more than 10 minutes before she showed up to see what happened. With all eight eyes. Pisaura_mirabilis_PSV_13jul...

Re: Olympus is leaving the camera business

It looks as if the desigers and optical engeneers have been busy lately. According to the new roadmap we can anticipate some interesting stuff before they are being "rationalized and optimized" by their new owners. Especially a new Pro macro lens in the 100mm area will be interesting for people read...

Is it correct to suspect that Topaz Sharpen AI has a key role in making sharp pictures at effective f:66?

I am really surprised with the capability of this software.
I have experienced what looked like minor miracles with shaken pictures.
