SILVERFAST EPSON 4990 SOFTWARE
SILVERFAST EPSON 4990 ISO

I always scan my negatives in Silverfast as 48-bit (color) or 16-bit (greyscale) positives with zeroed out adjustments and do everything else in Photoshop and Lightroom.A difficult 2020 that has blended into a difficult 2021 has made it harder for many of us to get outside and shoot, but that doesn't mean you have to neglect your photography.

Use a printing service that will accept TIFFs.įinally, I avoid letting the scanning software make adjustments for me simply because it's so inconsistent. JPEG is losslessly compressed and, especially with B&W, prone to posterization and blocky image artifacts. Try scanning as 16-bit greyscale - filesize will be smaller than a 16-bit color image and tonal information will be more detailed than with an 8-bit color image. Silverfast is doing things like 'Color Cast Removal' because you're scanning your film as a color negative. I dust my scans manually, since all software dust/noise reduction makes the image less sharp or has false positives. Silverfast may be falling back on software dust removal when hardware (IR channel-based) ICE fails. ICE doesn't work on B&W film (at least stuff that isn't C41) and the blobs you are seeing from Epson Scan are most likely a result of this. The holders with my V700 came adjusted to the correct height, but the adjustment is there for if your scanner isn't in the normal range. It would be nice to read an authoritative masterclass on this subject. Using the Silverfast help file is one thing, but every Youtube video I watch, the experts(?) always recommend not using any settings in the scanner software, instead recommending you use Photoshop etc for any adjustments. Even if I get a drum scan done, I probably want to post process myself a little. In the first instance I'd like to see a 20x30 to see how my post processing is going. Obviously I'm just the same as all permanently confused people WRT resolutions for printing and screen output.īut some pointers from an expert here would be greatly appreciated. Is this any different to TIF in terms of printability?ĩ: The service says it can print 20x30 from 5Mb JPGs - is this possible? Is this a common observation?Ĩ: When I export from Lightroom to Flickr, the largest size (Original) is 11414 x 14518 which implies 38x48' at 300dpi, but this is a JPG. But my gut is telling me that you need all this information in the file to produce the final downsized output at its best. If there’s no benefit in acquiring this file size in the first place, then there’s a good reason to avoid it. 1Gb files in Lightroom produce a real lag when you are doing spot removal and that sort of thing. So I'm sending the 95Mb file to see what it produces.ħ: I suppose I'd like to get scanner output which is close to the final output required. The first guy I spoke to said he needed a 200Mb file but upon further reading of their spec, this is only created for 16bit. But Silverfast then defaults to CCR (Color Cast Removal) Why? for B&W?Ħ: Lightroom imports this file OK but you have to be patient during develop processes, but I am working with a printing service/lab and they are asking for an 8bit 254dpi file output which is only 95Mb in size.

With Silverfast you can set Ilford HP5Plus 400 ISO - not sure what this would make the scan do - Epson Scan doesn’t offer such a selection. Or is it a setting I need to discover?ĥ: The 4800 Silverfast scan creates a 1Gb TIF file for 4x5 area. Silverfast 3200 does not give me the black blobs - not sure why Epson Scan has this threshold issue. The processing of iSRD in Silverfast takes forever.Ĥ: Scanning at 3200 ppi on Epson Scan gives me black blobs/squares in lots of places where it appears to be below some kind of a threshold. Correct?ģ: (Observation) Epson Scan is faster than Silverfast - not sure why. It’s an additional infrared scan which maps dust and scratch marks then processing the original scan to remove the mapped marks. I think Silverfast uses the same hardware feature but calls it iSRD. Correct?Ģ: I've been testing Epson Scan Vs Silverfast SE which comes with my Perfection V800Įpson Scan uses ICE as per hardware name.

In fact, the documentation doesn't even talk about these little height adjusters at all. My objective is to come up with a workflow to produce scans capable of 20x30' prints, and I would like, in the first instance, to provide my own scan - a drum scan by the service might be the final result if I'm happy with my own work.ġ: The height adjustment on the holder appears to do absolutely squat to the final image quality. Can anyone shed some light on some scanner queries? I am scanning 4x5' B&W negatives in the supplied holder.
