Dropping or pasting an image onto window and selecting a recipe, then please push the 'start' button to process the image.

Available Processes

autoBR / autoBR+U / autoRG / autoRG+U / Unsharp Mask / UnsharpEX

autoBR

(Tuned) B-R processing with automatic adjustment of the 'constant' parameter. The ratio parameters for R, G, B are pre-defined, which values exceed the value you can set on Photoshop/Paint Shop Pro. Approximately, it is "Blue channel minus Red channel" process. This process reduces contrast of clouds and enhance (colored) halos in a photo.

autoBR+U (autoBRU)

UnsharpEX after autoBR. The target image will be shrinked

autoRG

A variation of autoBR. Approximately, it is "Red channel minus Green channel" process. Try it for an image for which the 'autoBR' seem not to work well.

autoRG+U (autoRGU)

UnsharpEX after autoRG. The target image will be shrinked

Unsharp Mask

Unsharp mask with bigger parameters (well-known method to enhance minute difference of halo colors and/or intensities). The weak point is that it also enhances edge of silhouettes of objects hiding the light source. The target image will be shrinked.

UnsharpEX

A revised unsharp mask to defeat the weak point, which is less sensitive for larger difference of colors and intensities. The target image will be shrinked.
