Frequently Asked Questions
Can sharpening fix a blurry photo?
Sharpening enhances edge contrast, making images appear crisper. It can improve slightly soft photos but cannot recover detail from severely out-of-focus or motion-blurred images—that information is lost.
How much noise reduction should I use?
Start low (10-20) and increase gradually. Too much noise reduction creates a plastic, watercolor effect. Find the balance where grain disappears but texture remains natural.
Why add noise to a photo?
Film grain adds organic texture that many find aesthetically pleasing. It's popular for portraits, vintage looks, and masking digital artifacts. Also helps overly-smooth images feel more natural.
