On Rusty dome with stars in the Macro - Metal challenge (1 comment in total)

Well, it is understandable to overlook one word in a sea of rules (it happened to me more than once..), but the first word in the title?
Or, in other words, with the dome and the cloud both sharp at f/5, how can this be a macro?

On vanitas in the Mystery Still life challenge (2 comments in total)

Thank you!
The most fun was to prepare the skull -- playing with candles in such a way was something I was never allowed to as a child. Hurray for (nominally) being an adult...

On Objects 100 years old or older challenge (2 comments in total)

I think you should add "man made" or organic or similar to your rules. Every pebble or sand corn is far older than a hundred years.

In reply to:

yabokkie: there was a time that no body other than Canon could make high quality sensors. it's everyone but Canon now.

Samsung doesn't...
And then there's the Toshiba one in some of the Nikons

On ammersee 2 in the B&W Landscape challenge (2 comments in total)
In reply to:

Buzz Lightyear: I am looking forward to finding out what kind of camera was used to capture such a dynamic, sharp photo like this in 1970.

And now you know!
Well, gimp ate the exif, and I was too lazy to reenter it -- it was 2 o'clock in the morning, and neither full exif data or a capture date were requested, so I just entered an obviously wrong date (it was late summer 2010 I think)

Furthermore, I think a large or even medium format b/w film could beat a Nikon D60 in regards of dynamic range

On too close for comfort in the Butter flies challenge (6 comments in total)

Thank you!
I shot it at a zoo (http://www.zookrefeld.de/faq.html -- I noted that in my gallery, but somehow can't change it to public at the moment), so I guess it was just de-sensitized (there were hundreds of butterflies, and most of them were not shy, seems to be depending on the species).
Most of them didn't even notice the flash, only a big, blue one did.
And, as this is a 1360×1700 crop of a 16mp photo, I wasn't quite that close as it seems to be.
And for comfortable -- I think I tried for nearly 10 minutes to get as close as possible to this one (it felt longer), got cramps in my back and thought I was losing my eyesight (it was rather dark, and I had to manual focus -- more guess work and many tries). And the climate was tropical, while I was dressed for a german autumn...

In reply to:

Clueless Wanderer: ..The body position and everything about the shot seem to not be staged and genuine.
BUT. The guy is pretty damn clean to say he has just risen out of a trench held down by gun fire. Not even a spot of dirt on his knees or shirt. Hmm...

There is dirt on his knees, if you look carefully. It's just that the trouser legs move up (sorry, don't know how to say that better), because of the bending of his knees, so the dirt is on the trouser a little above his knees.
And there is dirt on the end of the trouser legs. I guess the earth was drier then at the somme or the other places better known for trench warfare, so it doesn't show as much as we're are used to from war movies.

On some glasses in a row in the Beautiful Wallpapers for Mobiles challenge (7 comments in total)

And out of characters...
Continued:

This created the outlines on the right side (and there is a reason besides composition that the left side is cut off...)
If that isn't clear: it's the same effect as here: http://www.dpreview.com/galleries/1017157792/photos/1157027/glasinglas?inalbum=glasses
(just inverted and smaller, and here I had to hold it diagonally, so that the line width for all glasses would be more or less the same)
Oh, and I used an external monitor for liveview, so I could see if I was holding the sheet correctly.

On some glasses in a row in the Beautiful Wallpapers for Mobiles challenge (7 comments in total)

Please excuse me if I don't reply to each of you seperatly, with that out of the way:

Uh, too many compliments, it's neither a masterpiece or that awesome.
In fact, it is only I would say 80% of what I wanted to achieve, and only after (for me) too much postprocessing (to eliminate the reflections between the glasses and some other lightspots).
But afterwards I knew how I could make it to, say 98%, and that this would be too much hassle (I'd need a different polarized light for each glass I think)
It was also the fourth or fifth try, so it's not as I knew how to do it from pure genius or so...

How to: well, just put the glasses in a row on a non reflective (as good as possible at least) surface, in a as dark as workable room.
I had single LED Light on the right front side (not so sure), and a cpl on the lens.
The white outlines are not all reflections of the light, but partly refractions of a middle grey plastic sheet I was holding to the upper left of the row.
(continued above...)
