My entry for the Black and White landscape challenge has just got DQ-d.

I got the DQ reasoning that I was not supposed to use more than one captures. After explaining that it was a single capture tone-mapped in Photomatix using different exposure-compensated versions of the same image, I got the extended reasoning:

You must create your entry from a single capture. Multiple exposures of the same capture are also not permitted.

Well, this is not stated anywhere in the challenge rules, and I have seen multiple entries (even in this challenge) using Photomatix or Topaz for tone-mapping. Since these are relatively novel tools, if they are judged too advanced for the basic editing rules, then they should be explicitly mentioned in my opinion. For that, the rules would needed to be modified, and only after that I would feel fair to disqualify entries using these techniques. I think, it is quite unlucky that the opposite order of actions is applied.

In the Basic Rules it states -

You must:

*
create your entry from a single capture.

In the Advanced Editing Rules it states -

You must:

*
create your entry from 1-10 captures of a single scene (defined as a scene whose composition/framing does not change). All captures used must be shot within the challenge submission dates.

That single capture was used to create 3 TIF files in RAW with different exposure compensations that in turn were used for tone-mapping in Photomatix. I did not use exposure bracketing which would have been the use of multiple captures.

But you created 3 files of different exposures... Therefore, the final entry was not created from a single capture, it was created from 3 different files, which you created from a single capture, but is still illegal... It clearly states that only one single capture can be used.. you took a single capture, and used software to create 3 captures... not legal... sorry...

This is where they got you.

"use only Adjustment Layers (or their equivalent). An Adjustment Layer is a special type of layer containing no image data that lets you experiment with color and tonal adjustments without permanently modifying the pixels. Adjustment Layers must be applied in Normal mode."

You can't have more than one layer with images.

This message from site council clearly states that Photomatix was now FAIR GAME..... not sure how \"within reason\" was ever established.. I\'ve been gone a while, so was this message squashed ????? I\'m not aware of any other method of using Photomatix that doesn\'t require you to make several versions of your same image.. Otherwise, what\'s Photomatix good for ??? I\'m not saying the DQ wasn\'t appropriate, I\'m just under the impression you could use this particular tool & it seems something has changed since I left... Clarification anyone ???

Editor\'s Note: due to popular demand, we have removed the restriction about Topaz Adjust. I have crossed this out of the original post (below) and will follow up in the thread. Topaz Adjust is legal for Basic Rules, subject to the rest of the ruleset.

Finally, please note that these changes invalidate our "had to remove URL since I'm new again" that prohibited Virtual Photographer, Photomatix, and Lucis Arts. They are fair game now, within reason.[/u]
Photographs that are currently in the voting stage that violate the above rules will be dealt with on a case-by-case basis. This is unavoidable during this transition period.

Now.... debate!

Photomatix can tonemap from a single file (legal). Working with multiple files (or multiple versions of the same file) requires layers, and the only layers allowed in Basic are Adjustment Layers.

OK, I have not realized this, and I had seen others using it so I inferred it was fine to do it.

So, after all it's my bad... I still think, it would be helpful to mention the different ways of tone-mapping in the rules but that is not a strong enough argument to revoke my DQ. It seems, I will have a week off (I had a self-DQ less than 25 entry ago).
It will save me from the embarrassment I could have got with this (not very seriously considered) entry for the sports:

Why would this be DQ in basic?

It wouldn't. Reread what was said about 2 DQ's within 25 entries...
