Re: Coolscan 5000ED, Überstrahlung
The CCD width is around 6cm, the 9cm limit is along the CCD axis. I just scanned 2 or 3cm along the CCD axis, just to show the hot pixels. Didn't seem that interesting to scan a 9cm long black stripe.

Re: Coolscan 5000ED, Überstrahlung
Well I guess I have to hope the CCD I bought is in better shape. That picture was made with a piece of thick black cardboard. It also shows that the LED backlight is quite uneven. The Red channel is particularly different from the 2 others. Brightness was pushed 4 or 5 stops in Lightroom to highligh...

Weird. I posted a link to the black picture that seems to have been deleted.

Re: Coolscan 5000ED, Überstrahlung
Both lines - the morse code and the continuous - are in the same direction, the scanning direction. Sorry, forgot to rotate the pictures. Yes, the line is 2 pixels wide. But it's not the only line. I have around 7 or 8 on the whole sensor. 7 or 8 groups of 2 pixels. I'll try the black slide approach...

Re: Coolscan 5000ED, Überstrahlung
Sorry, it wasn't that clear looking indeed.
First case : normal (somewhat) speedy scan (3 lines scan)
And in fine scan mode (Only one CCD line)
Conclusions : the lines tend to disappear when the brightness levels are above black levels. So I believe those are hot pixels.

Re: Coolscan 5000ED, Überstrahlung
That the CS5000 does not show flaring with negative film is due to the poor contrast in negative film, relative to slide film. Also important is that flaring goes by reflecting bright light into dark areas. In negative film, black and white show up reverse. - Also, slide films with poor density ran...

Re: Coolscan 5000ED, Überstrahlung
Thank you very much again for your detailled tutorial. I'll probably try it soon enough to check my scanners. Now I just need to make up my mind : I have a couple of sensor problems. My CS5000 is great with negative film. So is my CS9000. But with slides, the 5000 shows the infamous flaring and my 9...

Re: Coolscan 5000ED, Überstrahlung
I would be very interested, thanks you. I have a few coolscan with various flaws, that I would be glad to actually measure.

Re: Coolscan 5000ED, Überstrahlung
Thank you very much for you answer. It really is a game changer so the cost seems on par with what I was expecting and doesn't seem that high

Re: Coolscan 5000ED, Überstrahlung
Hi, What a great outcome ! I'd be curious to know how much it cost you to have your CCD unit recoated if it's not a secret. I am thinking about making a move in that direction as flaring on the 5000 is really too obvious and problematic. The problem is really less important on the Coolscan 9000 and ...
