Post your drum scans (aka the first official Drum Scanners thread)

Every Sunday is the stock market in Szczecin. Ektar dry scanned on SC11000 in RAW mode with my NegInverter plugin. Only white and black point set - film character preserved.

The top exposure is fantastic, every tone and colour looks perfect with great contrast. The lower exposure does not look quite so good to me. Fantastic scans though regardless, you are really getting the very best out of your scanner.
 
Please note this is without any tone or color correction - straight inversion from scanner RAW color space. My pluggin settings can be exported into Photoshop amp file.
 
Jack, will your plug-in work for any scanner if it's imported into PS? I'm having difficulties with my own inversion workflow which produces fine enough colours as it is, but lack consistency.
 
Here it is:

Scan negative as positive, 16 bit. Legend:

1) Negative Gamma - contrast value of negative (slope of densitometric curves) from datasheet, can be used for grey balance, typical value 0.6
2) Mask RGB - value of orange mask, write 255,255,255 if you use Levels
3) CRT Black Point - now obsolete, used in the past for CRT display to open up shadows
4) Image Gamma - 1 or 1,8 or 2,2 depends on platform/scanner soft. Gamma 1 (linear to intensity) is native scanner value except Kodak Cineon scanner which is 10 bit log.
5) Mark Clipped Area - like histogram in digital camera shows clipped places
6) Equal - locks White Point sliders
7) Equalizer - future function
8) Save Curve - saves amp file for Curves dialog window in Photoshop
9) Brightness - U type curve for adjusting overal brightness. Overexposed negative gives overbright image thus this value is usually negative.

With negatives scanner profile is rather useless. You can of course try calculate matrix profile with reflective target like VueScan does. 3D LUT profiles won't work - matrix profiles aren't precise but extrapolates better. Films do have character and for me this scene looks better than reality 😉

What kind of screen do you use?
 
I'm affraid FilterMeister plugin cannot be compiled on Mac. But it saves result as AMP file anyway (2D look up table). It's simple plugin and same things can be done with Levels/Curves - I nave collection of curves for that. I wrote it 10 years ago. Have also another with modern interesting GUI.

It's a superb plugin Jack!

I have just been playing with it under Photoline 18.01 (32bit version) and it works perfectly.

As it happens, I normally use ColorPerfect to invert all negatives.

With this one, my I simply inverted a RAW scan, no white point, mask settings etc (in truth... I don't really know how to - I am definitely an amateur), then initially corrected the histogram on the resulting positive, then finally the colour cast by adjusting each channel.

Easy for the negative scans I had to hand and vey nice colours. I am impressed. I like ColorPerfect's overall performance, but it's rather like a black-box to me... I for one would quite like to see the other with a modern GUI 🙂
 
I think TRC curve plus 3x3 matrix is sufficient for most lighting situations. With drums it's simplier because exposure is stable. With CCD scanners I observe less saturated colors. Wide gamut displays are more saturated thus images I shown may look oversaturated and strange.

I have HP LP2475w. Monitor calibrated with Spyder Elite3. Your image looks fine when I assign it s-RGB color space. 🙂
 
Wow, thanks jzagaja for that awesome plugin.
I think it just revolutionized my whole scanning for colornegatives _and_ for black&white =D
Thanks to that plugin I've finally found a workflow that works flawless for me... my scanning results in both color & b/w are sooo much nicer and richer.

Dzięki! 🙂
