How much to sharpen
Sharpening exaggerates the contrast at edges, so a little goes a long way. Start around 1 for a natural boost; push higher only for images that are genuinely soft. Too much introduces halos and amplifies noise — if the result looks crunchy, dial it back.
FAQ
Can sharpening fix a blurry photo?
It can improve mild softness by boosting edge contrast, but it can't recover detail that was never captured — a truly out-of-focus shot stays out of focus. It works best on images that are only slightly soft.
Does it keep transparency?
Yes — only the colour channels are sharpened; the alpha channel is preserved.
