is it sharpened?

[taigi]

Attached is a still of scanned super8. A fragment of a palm on the left.
My question is, is this sharpened or raw?
Not sure was sharpen button pushed.
Asking for a help of some eagle eyes.
Thank you.

Scan it twice. Once with sharpen button pressed and other time without it pressed. Then post that here

I do see some edge enhancement/sharpening, so yeah, I would not call this raw.

@Skiller, thanks, where exactly?

[Skiller]

It is visible at transitions of an almost black horizontal streak towards the greenish textured areas. If you look close enough, there is a lighter contour at those transitions. That's sharpening.

Looked at the image on PC. Yeah, it's sharpened

[taigi]

ok. it looks like some of Bsrgan?

Sharpening is usually a part of digitizing images. Cameras/digitizers usually use a bayer pattern sensor:

https://en.wikipedia.org/wiki/Bayer_filter

Those raw beyer subpixels are converted to RGB pixels by mixing, blurring and sharpening, the sub pixels. So unless you are getting raw beyer pattern images the images you are getting are processed images. And, of course, even if you get raw bayer pattern images you have to process them in order to create RGB images or YUV video.

From the Wiki page:

A camera manufacture would call that a 36 pixel sensor and would produce a 36 pixel RGB image from it. But it doesn't have 36 red, 36 green and 36 blue sensors. It has only 18 green sensors, 9 red sensors and 9 blue sensors. 36 RGB pixels are created from those sub pixels by mixing, blurring, and sharpening. But the resulting image can't resolve 36 different pixels. This is the lie that all camera manufactures tell.
