Affinity Photo, Aplicar Máscara rango de luminosidad en JPG o PNG


Recommended Posts

Welcome to the Serif Affinity forums.

I'm not sure I understand the question. Are you referring to the Live Luminosity Mask that is possible in Photo 2 already? Or something else?

Si, exactamente.

Cuando trabajo con la máscara de Rango de color en tiempo real, puedo aplicar la máscara a un JPG y funciona muy bien, pero cuando intento trabajar con la de rango de luminosidad, se comporta extrañó, no se aplica a las capa de pixeles, solo funciona en las capas ajustes.

Thanks.

Can you provide screenshots or a screen recording to demonstrate your problem? Please make sure the complete application window is included, with the Layers panel and the affected layers also showing.

Thanks for the screenshots.

Unfortunately, I still don't understand what it is that you want it to show you. The Mask is applied only to the selected layer (which is an Image layer), and it would allow the layer below it to show through.

Here is a screenshot of a sample I just composed to show this:

  1. Without the Live Luminosity Range Mask:

  2. With the Mask added, as you have it. The Mask is controlling the appearance of the JPG file (the top layer) and what shows through from the bottom layer.

Thanks. I am not familiar with what Photoshop does. I can only say what Affinity Phoeo 2 does, and I think what it does matches the documentation:

Use non-destructive Luminosity Range Masks to mask an image's tonal range based on its luminosity values.
