![]() ![]() Yea, the muti-exposure feature now in Silverfast really interested me if it could increase the dynamic range of my scanner. Place for both being honest, though if I had nothing.I would pick Silverfast is very comprehensive, but I just prefer vuescan. I didnt upgrade to the multiscan, as I was a bit niffedĪt silverfast for not offering it for free, I spent extra on the I do have silverfast, and Iĭo use it a bit, but I just feel I get better more accurate resultsįrom vuescan. I mostly get better results with Vuescan. Obviously, the "real time" view of any manipulations in Silverfast Silverfast has many features, but I would still welcome any comments. I realize this may not be a fair comparison given Overall comparison of the two programs from a quality of output Noise in the scan, it appears to work well enough.ģ. Serioulsy I use it for mainly 3/4 scans, to wipe out any chance of If you are scanning at 7200 dpi, 10 times plus How well does Vuescan multi-scan function work? Worth the extra When you refer to slides, are you referring to both Kodachrome and E-6 slides?Ģ. With a bit of tweaking, even my oldie slides are nice Works very well on slides, you can run it on its own, or in PS. Slides, they dont work well with infared removal, or ICE on other It replaces scratches with more skill, IMHO. It works pretty well, though I stick to low to ![]() Infrared function, it shouldn't be used on silver-based Kodachrome,įrom what I understand. Loss? Does it work on Kodachrome slides? If it is indeed an How well does Vuescan dust and scratch function work? Any detail I also upgraded to get the multi-exposure feature.ġ. I have a Plustek 7200i film scanner, so I am just learning to use However, if the resolution is 2400 dpi in this example, then the number of samples can be up to 4 since the stepper motor can scan at 9600 dpi (4 times the optical resolution).Just curious as to some users experience with Vuescan and Silverfast. However, at optical resolution (for instance 4800 dpi) the maximum resolution of the stepper motor is often just 2× the optical resolution (for instance 9600 dpi). The way it’s implemented is to scan in the stepper motor direction at a higher resolution than in the CCD direction. ![]() The maximum number of samples is resolution-dependant. Ed Hamrick - the creator of Vuescan - gracefully explained the “problem”. I will try to redo the scans on a USB3 port, maybe i will find an explanation. I really can’t tell what is the limiting factor. Then, let me show you the results for the same material, scanned at 2400 dpi: Number of samplesĬan someone explain the last result (one sample - two minutes 49 seconds)? Again, i got some crazy timing for scanning at 1200dpi too: Number of samples So… when i decrease the number of samples, the scan time grows?! Ok, maybe the option Number of samples does nothing when scanning grayscale, and the small differences come from my way of starting the clock etc. To have an idea of what Number of samples cost me, i’ve started to scan a sample at highest optical resolution my scanner is capable (4800dpi) and i got these results: Number of samples So, last night i wanted to see if the improvements are to be seen with the naked eye and if the procedure worth including it in my workflow. Multi-sampling is available only on a limited number of scanners.Īdvanced Option: This option is displayed when the scanner is capable of multi-sampling. Multi-sampling is preferable as the scanner head is positioned once, which ensures that the same area will be exposed for each sample. Number of samples is similar to Number of passes. You should experiment with your scanner to see which balance of speed and accuracy is appropriate. This option will slow down scanning because the scanner is doing more. By taking multiple samples and averaging the results, the effect of inaccurate exposure is reduced. Noise will appear as one pixel whose color or tone is different than surrounding pixels. This is a useful feature because any one exposure may be inaccurate, resulting in noise in the output. The results for all samples are averaged. ![]() As the scanner head passes over the media it makes multiple exposures for each location. This option is available for scanners that support multi-sampling. Let me tell you about single-pass multi-scanning: some scanners (mine included) have the capability to read a line multiple times and average the result, in order to minimize the noise. ![]()
