I only see reflections, but no refraction.

Mirrors reflect, but don't refract.

On photo 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 photo 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...

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.

Thank you all!
It's nice whenever another likes my silly ideas ;-)

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 photo 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 photo 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)

On photo Fremen Walk Without Footprints in the Dune, the spice must flow challenge (6 comments in total)
In reply to:

FNG303: The Imperial Sardaukars are the equivalent of the Imperial troopers.

Nerd! ;-)

Yes, I guess you're right.
Afair the progression was: nearly nobody used shields because nobody used lasguns because that could blow oneself up.
(and cheap remote operated kamikaze lasguns were forbidden...)

And weren't the sardaukar rather quickly dispatched? As they were a reference to later days janitshars and mameluks: once invincible, but at "the present" just living on their former fame.

But the Sardaukar didn't shoot, because, as how the shields in the dune setting work, this would kill both the target and the shooter.
It was hand to hand combat, if i remember the books correctly (20 years past...)

Nice, i don't know if I want to spend that much time there, but as motiv for a photo it is great, as is how you shot it.

In reply to:

Slynky: Congrats on you finish. Very imaginative. It should be framed and hanging in a room with contemporary/modern design.

Thank you!
I don't know if one should hang it on the wall, if you look at it too long, something may look back ;-)

LeeStar: Awesome photo, and very imaginative how you created the shot. Thanks for sharing your method with us!

Thank you!
I learned that, with this and similar photos, it is important to show that they aren't cgi, to get not that much 0.5 votes (well, one couldn't resist ;-) ); they just should look like cgi at first glance.

On photo Alien Ribs in the Abstract Photography challenge (4 comments in total)

It is a build it yourself paper lamp?
I have a construction kit for one, and the shapes look rather similar.
