It depends on the monitor you're using also, and how it is adjusted (or if it is adjusted). ... |
Question on Duotone image convesion. Based on the basic ruleset, filters are very limited. Does that mean that special effect filters that automatically convert an image color scheme are also illegal? To stay within the ruleset wouldn't adjustments have to be done manually using Hue and Saturation, Colorize, etc...?
From Basic Rules:
"Filters: The use of filters (or non-Photoshop equivalent) is strictly limited. Any filter or stand-alone utility designed and used to preserve the integrity of the image and/or reduce the effects of noise, scratches, etc, are permitted. These include but are not limited to the Sharpen, Unsharp Mask, and Dust & Scratches filters, and standalone image cleanup utilities such as NeatImage. However, no effects filters may be applied to your image, with the exception of Noise and Gaussian Blur, which are allowed."

| Hue/Saturation, Curves, etc. are adjustments and not filters and are thus permitted under the Basic rules. A "special effects filter" would probably not be permitted, because there's no way to verify whether or not "selections" are being made "behind the scenes." |

Not sure I completely understand your question. A duotone conversion is usually made in the following steps.
1. Convert to greyscale. (I prefer Channel Mixer, but Hue/Sat adjustment layers work too.)
2. Set Mode to greyscale.
3. Set Mode to Duotones (Choose colors for Duotone conversion)
4. Set Mode to RGB
I don't know of any filters that do Duotones, so I'm not sure what kinds of adjustments they do.

I thought there were effect filters that you just select the color and it applies the changes for you automatically. In PSP X there are two ways to get sepia for example - you can select the Effects/Photo Effects/Sepia Toning - or, you can do it the old-fashioned manual way by selecting the hue/saturation/lightness levels under Hue & Saturation Adjustments.
One is an "Effects" filter, the other is an adjustment. I know adjustment tools are legal, but it sounded like effects filters weren't when I reread the Basics ruleset. That's all. ;^)

Certainly for the purposes of the duotone challenge (actually for ANY Basic Editing challenge) a "filter" that ONLY applies a sepia or duotone effect is legal. Though one could view this as an "effects filter", sepia toning or doutone is allowed, unless layers (other than adjustment layers) are used in the process, and if the effect is applied to the entire image (no selections).

| Yeah....I would think the "photo filters" in Photoshop would be ok....That is how I usually do Duotones....DeSaturate, and then use one of the "photo filters" image/adjustments/photo filter. But who knows...the rules confuse me sometime :) |

ok a little off topic but you can use curves in Basic? |

Toning picture is one of first discovery in dark room so it is against all knowledge in photographic not to permit it .. ice
