In Basic rule set, I know unsharp and Gaussian blur are ok applied uniformly to entire image. How about high pass? It is listed in my editing software under "focus" adjustments along with unsharp and Gaussian blur.

you can use highpass but not on a new adjustment layer. The way I usually use highpass is on a new layer set to softlight blending mode. That would be illegal in basic. But if you just want to use strait highpass I think it should be fine.

Which software are you using? High-pass normally needs a second layer to do its job, and that's not legal in basic no matter if the software is creating the layer, or you are. I would suggest that you ask the Site Council to give you a ruling on this before you use it for any challenges. Submit a "General Inquiry" ticket under Help>Contact us from the main menu, and include as much detail as possible, including the software and version you are using.

I remember asking about one of my first entries submitted about using "high pass" in Photoshop CS5. I asked the council and they said that it was not legal due to it automatically creating a new layer to do it's job. But, things may have changed since then? I dunno.

All good to know... Using Capture NX2. It gave me options to adjust the amount and the opacity, but as you said, it is likely creating a layer behind the scenes. I'll just avoid it in Basic.

Thanks,

Same thing when I asked about PSP X.
