In Topic: Spirit 2k log scan or HDR Scanity 2k log scan of 16mm footage

But I think that dismissing the scanner outright because of issues that only some people are having, doesn't make sense. The fact is, we're doing tons of work on this machine and haven't had any complaints about the dynamic range, noise, tap lines, etc. When it comes down to it, what matters is the final scan, and the results the client gets. Our clients are happy with the results and so am I.

I am not dismissing the scanner at all I bought one and I am buying more from LaserGraphics.

I am not having problems with scanning film I just scan film on the appropriate machine as I am not limited to one scanner.

 

The Scan Station is a great machine for many scan tasks and many customers are extremely pleased with the look of the scans we make from it.

 

That said is it a sustainable business model for LaserGraphics to sort through dozens of JAI cameras to select between D, C and B grade CMOISIS sensors for each customer? Did you pay them for that? If you got that for free I think it was a poor business decision on Stefan's part which frankly reflects negatively on the company. If you did pay for this service it should be on the price list for the machine.

 

Remember that JAI sells thousands of this model of machine vision camera to Traffic companies and the Military and film scanning is hardly a high volume customer, what is the business model for laserGraphics there, how much tolerance for low volume BS will JAI put up with?

 

So I buy a machine and the guy down the street buys a machine and you buy a machine and we all pay the same price but the three machines all make different results? So me and the other guy see you got a better machine and complain to Stefan and then he has to spend tens of thousands of dollars in material and time to redress this, how does he stay in business?

 

I can see that the inconsistent CMOS chip manufacturing at CMOSIS (don't they make red sensors? speaking of inconsistent)  will make sensors with degrees of FPN issues but the sensor is inherently flawed in several aspects and I know when we bought our machine Steve was asking about other sensors with similar pixel count and better performance, I think this is a well known thorn in the side of LaserGraphics.

 

I also remember you saying on FaceBook that the 2-flash HDR on Scan Station almost eliminates the cmos noise issues, which is what I have heard generally.

 

I think the machine is great and that the engineering team has done a amazing job turning a very inherently flawed sensor into a machine which performs beyond expectations but IMO it is not perfect for everything.

 

YMMV

One of the applications of that camera is traffic cameras, yes. The main commodity use for this type of high speed/high res camera is circuit board inspection - high speed, high resolution trace inspection. Either way, who cares? I've got to be honest, Rob, I don't get why you're so down on the sensor in a scanner you own!

 

I like our Scan Station it makes good pictures but I frankly do not believe you when you say your Scan Station is one magic unicorn machine without the fixed pattern noise issues and limited DR from the CMOSIS CMV20000 based JAI and I also doubt that a firmware can change the fundamental physics of that sensor.

 

Other Scan Station owners do not make these claims and if this is true then LaserGrpahics should be rolling out updates for all machine owners but when I asked I got no response from them.

 

I can tell you that the Xena with the Kodak 16070 at 82Db of DR really blows the Spark away in terms of dynamic range.

Well to be clear the new CCD line arrays in the Scannity have vastly more DR and better S/N than a off the shelf cmos sensor made for traffic monitoring and probably better DR and S/R than a two flash "HDR" on a cmos sensor based scanner.

 

The Scannity arrays were build by Kodak or Dalsa specifically for scanning film not for telling when you ran a stop light, they have bigger pixels and more well capacity and little or no fixed pattern noise.

Bit Coin.

Oh yeah right Krypton-Currency.

 

Speaking of can I talk to you about my new Hula-Coin ? It's the best!!! way less sketchy and bubble like than Doge Coin.
