Timlu, what you adressed is one of the problems Bear_Music, the Site Council and I discussed on one of the first pages. Photoshop does use methods in the background which are not legal when done step-by-step. This does present an incongruity, but it does not allow users of other software to exploit the inconsistency.

In short, creating scripts will not solve the problem.

I totally agree that creating script will not solve the problem with the inconsistency. My question was; is it OK to use the scripts in GIMP (or the plug-ins in PSP) to achieve what PS can do? And, if so, is it then OK to make your own scripts or plug-ins to achieve whatever you want? If the answer to the first question is yes, this would mean that the answer to the second question is yes. If the answer to the first question is no, this would mean that you introduce a rule that stipulate what software you must use to enter a challenge. This is something like having a challenge wich only owners of Canon cameras are allowed to enter. Sorry, you have a DQ for using a Nikon camera in this challenge...

As Manic said earlier, for basic editing it's the methods you use, not the ends you achieve which determine the legality.
If the rules were consistent, then Duotones/Tritones should be forbidden alltogehter, which would be stupid as well.

To sum it up, we are narrowing in here on THE major inconsistency in the basic rules.

For just one example: SC have ruled that Photoshop CS2 "shadow/highlight" adjustment is legal in basic rules. But this adjustment is just a single-panel evolution of the cntrl-alt-tilde contrast masking technique that is available in earlier PS editions. You create a lyer masked for highlights and a layer masked for shadows, change the blending modes on each, and use layer-opacity changes to merge them together. This is exactly what "shadow/highlight" does in CS2.

The rules, as they stand now, because they are tool-specific rather than results-oriented, allow those who have bought the latest software an advantage over those who still work with earlier, less-automated versions.

This is what I'm getting at. The duotone option is not available in PSP. Next step: do you consider the means or the ends for duotones? I followed that recent thread about DrJones DQed image a bit, so I guess it's the ends that count?


In PSP8, if you go to the "help" then "index" and put in the word "duotone", (or even if you look under the information for "colorize", it will mention duotone) you will see a tutorial, if you will, on how to produce a duotone image using PSP.

1. Convert to Gray Scale
2. Increase image to 16 million color bits
3. Take to "colorize" and choose color and sat

Pretty simple procedure in PSP really. Nothing complicated.

You can also do the same effect using a similar conversion in this way:

1. Go to "image"
2. Select "split channel"
3. Select "RGB"
4. Take the blue, green, or red image and .....
5. Take to colorize and choose color and sat

Both really have the same effect, but process one is what PSP tells one to do to achieve the effect verbatim. Whereas process two was just something I stumbled upon.

To make the difference between monochromes and duotones clearer: try to create a tritone with Rose's method.

Nice tutorial!

I never really understood how to use blend ranges effectively, your examples really helped bring some clarity into them.

Thanks!
