The german specialist for slide technology Reflecta has introduced the new CCD scanner ProScan 7200 for quick image processing at the end of november. The ProScan 7200 scans 35mm negativ and positiv filmstrips as well as framed slides with an optical resolution of 3600dpi x 3600dpi and a color depth of 48bit. An additional infrared channel built into the scanner enables automatic dust and scratch removal.
The SilverFast scanner software was specially adjusted to the technical details of the ProScan 7200 for achieving optimum results.*
More information on SilverFast for your Reflecta ProScan 7200 as well as downloadable test versions you can get here …
* Note: SilverFast supports the ProScan 7200 under Windows 2000, XP and Vista by now. Versions for Windows 7 and Mac OS X will follow early in 2010.

The human perception is aligned to the recognition of edges and lines. So the sharpness impression of photos can be increased by contrast rise of small brightness changes. Conventional sharpening functions often increase the detail contrast of the complete image in general and therefore strengthen also any image interference of the original, details get lost. In contrast the SilverFast Unsharp Masking USM carefully raises the contrast at edges and lines. The sharpened images appear losslessly much more detailed. [Read more →]

In the Previous article I described the different parts of the resolution control panel in SilverFast, and how to use the resolution slider.
This article deals with the second part of the resolution panel, the “Q-Factor and Screen” values.

Where Q-Factor stands for Quality factor and Screen value is related to the lines per inch used for printing.
I know, it looks very complicated and confusing. But don’t worry, the default values are optimized to obtain the best quality possible.
These two values are part of a formula derived from the analogue printing world where screening technology is used to create different shades of gray (if you carefully look at a printed picture in a magazine or newspaper with a magnifying glass, you will be able to see this matrix of dots which create the picture).
As I mentioned, the formula is by default optimized.
The short and understandable version of the formula is:
Q-Factor x Screen (lpi)= dpi
The purpose of this is to scan pictures with the optimal resolution for analogue printing and optimal file size. If your pictures are to be printed with a digital printer (like the one in almost every household), this should not be a matter of concern for you (and it is recommended to leave this as is).
If you are working with magazines and newspapers then you should discuss this with your editor and printer to exactly know the values and the sizes they will be printing your images so the quality loss is reduced to its minimum.
The use of this values does not necessarily mean true optical resolution, it is likely that some sort of interpolation will take place (regularly for downscaling).
A more detailed explanation can be found here
In the next article I will explain the scale and output values equation (part 3 of the resolution panel) and how this can be used combined with the “resolution slider” or the “Q-Factor_Screen” formula to obtain the desired results in terms of resolution.

SilverFast has a very complete set of controls for managing the scanning resolution (although sometimes complex to understand). When mastered and properly used, these controls can prove very effective.
The resolution control panel can be found under the “Frame” tab and is basically divided into three: [Read more →]

The 5600F is a popular flatbed scanner with a transmissive unit, which scans almost any original like photos, slides, filmstrips and documents. The scanner features LED technology and is therefore ready for scanning without any heating period. Windows support: For the first time the many additional features that SilverFast offers are now available for Canon’s 5600F – for perfect scans.

Nikon has created top notch film scanners (probably the best dedicated film scanners) for some years now, being the Nikon Super CoolScan 5000 ED the top of the line on its 35 mm scanner line. However, working with its film holders can prove complicated.
This is true for the film holders SA-21 and SA-30 which are used for scanning 35mm film stripes of up to 6 pictures.
The next steps describe a good way on how to operate these film holders. [Read more →]

The Nikonians are a large online community of Nikon users. Jason and Rick, the Nikonians’ “Image Doctors”, regularly podcast every two weeks on topics around imaging and photography since the end of 2005. In podcast number 105 they feature a thirty minutes interview with Gerhard Wolff of LaserSoft Imaging. They are talking about the changes that scanners and scanner software SilverFast have made during the last years. [Read more →]
