JPEG Export Presets: Make bicubic the standard

Recommended Posts

I just realized that all baked-in JPEG export presets have their resampling algorithm set to "bilinar".

I may be wrong but as far as I know one should in general choose at least bicubic for a sharper result even if it takes longer.

Is the preset optimized for export speed? I think at least the maximum quality preset should use bicubic.

You seem to be equating quality with sharpness.

From what I've read, some images will benefit from becoming sharper, but others will suffer. I think the user really needs to make the choice when additional sharpening is being added.

I would prefer this setting to be sticky, so it would keep the last used setting.

Wouldn't creating a new preset the care of that for you?

@Fixx In my case this works. I don't need to change anything on a second export.

In this topic I just wanted to express that I wonder why someone doesn't want that extra sharpness from bicubic resampling, but @walt.farrell is right that I personally equate quality with sharpness of an image, but this must not apply to everyone.

Indeed it does. Seems that preset is sticky even though resampling method on its own is not.
