those scans look very good to me, the colors in the first shots are really nice. Did you apply any sharpening in post? Be sure to avoid USM with the scanning software though.
Thank you Morfeus! I am glad to hear that as I am not feeling yet confident in my abilities. It's certainly more complicated than simple raw conversions.
I ticked the sharpen button in Vuescan as I found out it only applies very mild basic sharpening. I only applied USM 0.5 100 0 after resizing to 600x900.
PS: By the way, I am noticing two bands on each of the shorter sides of the frame that are forcing me to crop out the last few millimeters in length. Not a big deal but a bit disappointing nevertheless. I wonder if these are reflections from the film holder or scanner defect. I will try to scan a full frame later on and post the effect here.

A couple from my last engagement session... a mixture of Canon 1V and Mamiya 645 AFD all shot on Portra 160. I love this freaking film for shooting people!!!!! https://www.fredmiranda.com/forum/ufiles/06/573106.jpg
The flare here is very well placed! Could you see it in the finder?

Here it is guys. Anyone has any idea what would be the cause?
I think this is normal and I have that stripes too. Don't have my negatives here, but I think it has nothing to do with the scanner, but the film itself.

I don't think so Heinz. My negatives do not have these bands, neither the slides, but they show up in all the scans. To rule this out, I even scanned older slides that were previously scanned with the Nikon (which didn't show stripes) just to make sure it was not the new camera's fault. Well, I guess I should try to shoot just a bit wider.
By the way, I also noticed that after I crop out the bands, I get exactly 2:3 image proportions, so it seems like the scan has been horizontally stretched and the excess part shows this band. Anyhow, no big deal, just curious.
Well, then I don't know. I just remember that I have seen those stripes in the preview window of both, the Reflecta and the Minolta with Vuescan and the Minolta software and cropped them.
as I found that the usual strategies for digital do not work so well with scans. You actually need 3 scripts before you apply the normal (resize-) sharpening: de-noise, content sharpening and output sharpening. He covers that very nicely in the book with real world examples.

Thanks for the info, Heinz. It must be typical of some scanners then
And thanks also for the recommendation of this ebook. Would be very interesting to learn how to properly sharpen film scans.

Those bands are probably due to flare in the scanner optics, caused by light shining through the clear areas on the negative in between the frames.
Agreed, it does look like flare. It could be more likely caused by light leaks from the edge of the diffuser sheet which is above the LED lamps in this case.
Could be, but I know Coolscans suffer from flare too. I've seen it on the edges of film when scanning stuff like Kodachrome. When I said optics, I meant the whole optical path of the scanner. You might be able to fix it if you can mask off the negative by using a different holder or something. But anyway, when scanning things like Kodachrome on a Coolscan, you can get flare that bleeds over from the highlight areas. I don't own a Coolscan 8000 or 9000, but I think they have more flare problems when scanning negatives without using the proper mask as well. Apparently, in the Coolscans, the flare occurs mostly because of the cover over the CCD or dirty optics.
Regardless, whatever the cause is, I'm not sure what you can do about it. Fixing a light leak in a scanner sounds like a pain in the butt. Something you could try is to center the gap between two frames in the middle of the scanning area. If it's flare from the light shining through the gap, one might think you would see it bleed over onto the two adjacent frames.
I get sort of the same stripes on 135 film with my Epson V700, but on the long sides. In my case it's because of reflections from the film holder, not the scanner optics.

So it seems this is a common occurence when scanning 35mm film, regardless of the cause. Thanks for your input Martin.
