summicron: several nice entries.
some dismaying sandbagging.

Yes, interesting voting pattern...
The last challenge with the same winner ( http://www.dpreview.com/challenges/Entry.aspx?ID=612740) has a similar pattern.

On (half) empty in the With that glass of red wine challenge (12 comments in total)
In reply to:

Five Piece: However you got this, spectacular final image! Could you please tell us a bit about your lighting setup, that is always a challenge working with glass.

Yeah, the lighting... before I always had the light-source (then some neon tubes) under the glass, lighting it from below. But with the wine, this ends up getting too dark (for the wine, or else the rest is overexposed).

That time I especially wanted to make photos with red wine, after getting an idea for a rather easy lighting setup.
It's really just a softbox (well, a light tent used as a softbox...) shining against a white plastic sheet in the background, so it is a very soft and uniform light. The plastic sheet was leaning against a dark background, which emphasizes the borders of the glasses (it makes them darker)
And with glass I always use a cpl, so I can control (if not always eliminate) the reflections, and how the glass-borders look (hard to describe, it just has to be tried)

In reply to:

jojosardez: I would be surprise if this will not win this challenge. Great shot!

I really appreciate your comment, and the comments below, so please don't take this in a bad way, but I think in the spirit of the challenges entries shouldn't be commented on while the voting hasn't finished, because that may influence the scores given (in both ways, good or bad)

Again, thank you very much for your comment, but please only comment after voting has finished.

And, wow, a score of nearly 4? Seems I really found and eliminated all the fingerprints on the glasses ;-)

Thank you all!
I used a 7 inch monitor and liveview to help arranging the glasses (great help, because I didn't need to run back and forth...), and then didn't noticed that the first glass was a little out of line (I was too occupied with getting the upper part right).

So the "half" of the title also indicates you are seeing only half of the glasses -- I cut the photo in half and mirrored the left side.

And it makes me a feel a little guilty reading about the great composition, while knowing of my blunder shooting it... (and I even used rulers and a string to get the alignment right, just to be my usual bumbling self at the end...)
But, after all, with my means, I would never have got the symmetry that perfect, so perhaps I would have done the mirroring thing in pp anyway.

I only see reflections, but no refraction.

Reflection != refraction

Mirrors reflect, but don't refract.

On 12 copy in the Images Refracted by Glass (I do not mean your camera lens) challenge (1 comment in total)

Isn't that a reflection, and not a refraction?

On DSC01557 in the Images Refracted by Glass (I do not mean your camera lens) challenge (1 comment in total)

Well, it's neither a visible refraction, nor was it taken after the announcement date...

On Less Is More challenge (11 comments in total)
In reply to:

christian jacob: "Digital JPEG photos only" -- does that mean the photo must be shot as jpeg (not raw), or only that it wasn't shot on film? Or, in other words, are photos shot as raw and later developed okay or not?
As one cannot upload any other format than jpeg here, no film or only shot as jpeg are the only 2 possibilties I can see.

Thank you for the clarification -- as I mostly shoot jpeg+raw (and dispose of the jpegs later) I wanted to know if could enter.

It's nice whenever another likes my silly ideas ;-)

In reply to:

santamonica812: I love the shot, but it's an painfully obvious violation of the rules. Dreadful job by the challenge host. Since that host fell down on the job, I will apologize to the 3rd Place finisher (#2 also was hugely in violation), since you are the deserving winner. Sorry that 2 people didn't care about submitting images within the rules, and sorry the host was incompetent (or indifferent).

The 2nd place is by the same submitter as the first place...

How is that a hdr? (Or a "hot" photo, as you entered it in that challenge, too)

On warp 2 in the Abstract in b&w challenge (5 comments in total)

Thank you!
I am a little unsatisfied with it, as I didn't bend the grating properly, so the pattern isn't parallel to the borders.
On the other hand it shows that it isn't a cgi, but created with "real stuff" (from a "do it yourself" shop).

On AL7_2760_F150r in the Perspective correction challenge (3 comments in total)

Great!
Have you "shaved" off the lens hood of the samyang to get more out of it with your D700?

You should made your self made rectification program available, at least this photo is a great endorsement of it (and you as a photographer, of course, as it is the composition which make this so great)
