SilverFast, a company known for making remarkable software that gets more from a scanner than the manufacturer’s software can, has taken quality to the next step. SilverFast has released the SilverFast Archive Suite. This is a two-disc set. The first is the SilverFast Ai Studio that now allows not only 64-bit HDR multiple scans, but on specific scanners (we used the Epson V750 Pro), it even unlocks the infrared channel. In a second, I will explain why that is so critical.
The 6400 dpi HDRi scan of a 6x7cm transparency creates a huge file of 1.35 GB that is rich in data. With HDRi scanning, there are no corrective controls available. You are truly getting a RAW scan. The image will appear darker than you would like, but this is only the first scan. You can also scan in 32-bit HDRi grayscale. Scan all of your images and save them in a folder.
In the second part of the Suite, reopen the SilverFast Launcher, but this time, activate the 48BIT HDR Studio. This opens the VLT (Virtual Light Table) where you will see the images you previously scanned. It is in the HDR studio that you make your general image adjustments from the information collected in the RAW scan.
Now comes the really cool part. Click on the SRD (Scratch Removal) button to change the button to iSRD (infrared Scratch Removal). Then click it on again to open a second button for an SRD control window.
What took place during the HDRi scan is that SilverFast Archive Suite unlocked the infrared channel. This is now going to be used to identify and remove dust and scratches. This is a very different approach than previous dust and scratch removal, which also lowered resolution by diffusing the image to remove debris. Check the iSRD button, and then
click PREVIEW to reveal the infrared channel of the scan. What comes up next is a highly magnified section of your image with a lot of red splotches. This is all of the dust, scratches and miscellaneous debris on your transparency or negative. Either adjust the Detection slider or check the AUTO button. The red splotches will grow considerably. Next, hit the PROCESS button and the infrared channel will be used
to remove the debris. Most important―it does so without softening the image resolution. The above images show the full image and two sections, one with the dust and the other with the dust removed using the infrared channel. The results are amazing.
You can also lasso more difficult debris and use regular SRD controls to remove them. With the transparencies I tested, the little debris left over was easily removed with the HEALING TOOL in Photoshop. For more information, contact www. SilverFast.com.
