![]() ![]() Of course with test targets taken under ideal conditions with high resolving film pixel peeped greatly magnifies the difference in resolving ability between these scanners. This one I used Fuji Velvia (RVP) and scanned using my Coolscan, Epson V500 and Epson V7XX.įuji RVP50-03_18 Coolscan 5000 full res -> I then used optimal camera settings (tripod, MLU, sufficient lighting for high enough shutter speed across all apertures) and various film types. I printed out a 4 X 4 arrangement of res charts on tabloid paper to test my lenses. ![]() The scan block will return to the home position on the next power on.Īnyway, what you can see through this can be resolved by the Coolscan's 4000dpi and the difference between that and the Epsons are as you have found - not close. Assembly is more difficult with the scan block at the home position. The scan block will be movable by hand as needed and will lock if pushed back to the home position. Working from the rear lift the case off the base then unhook the snaps at the front and unplug the switch plugs. Remove the screw at the bottom of each hinge socket. Remove the lid by lifting straight up at the hinge. To open that scanner start a scan then pull the power plug once the scan block has moved partway into the scan. I have seen it turn loose and allow a side to drop slightly. The bed glass on the 3200 is attached to the case with double sided tape. Target is a 2 inch X 2 inch standard printed on Kirkland glossy photo paper on a Epson 2200 photo printer at 2800 dpi. the target will not fit properly in the film/transparency holder. Left to right: target scanned as document, scanned as transparency positive with target on bed glass, target laying on top of film holder, target inserted as a piece of film in the holder. OK, it does not make a significant difference.Įpson V500, EpsonScan, 16 bit grayscale, 6400dpi scan resolution (scanner optical limit) saved as tiff then converted to jpeg in PS. Once you know the correct height then lexan, plexiglass, or acrylic the correct thickness can be used with a single layer of black paper for the mask. ![]() Cut out the image area and secure the edge of the negative/positive to the frame with painters tape as it leaves no residue. Use a loupe and find a critically sharp negative, mount it in the film holder and scan it in transparency mode.īlack poster board or similar can be used to make film guides for scanning. This may be causing an erroneous focus height. The fact that the light must reflect off the stainless steel then back onto the set of mirrors in the image path. Transparency Scan: Light from the cold cathode florescent lamp in the transparency adapter is shown through the transparency material onto the set of mirrors that reflect the light into the lens and then the sensor. While your testing procedure is sound I question the use of a non transparent test object.ĭocument scan: light from the cold cathode florescent light source is reflected off a mirror onto the document, in the test case a stainless steel gauge, which reflects back down to another set of mirrors then into the lens to the sensor. What is the most practical path forward? I won't bother using this scanner if I can't get sharp scans from it. But I wonder why this isn't an option with flatbed scanners in the first place. Use a single piece of ANR glass to hold the negative flat on the platen and software control to put the 3200 in flatbed focus mode but have the transparency light on. I use a glass negative holder for enlarging so cleaning the 4 sides of the glass holder doesn't bother me.ģ. But if possible I could easily scan anything to include 617 negs, 120, 70mm, 127 (46mm) and 4x5 film. I don't know if I can get thin ANR glass that is 1mm thick or less. Use two sheets of ANR glass to hold the negative between them and shim the bottom glass to be 1.33mm high and just place in on the platen glass. And I need to find a 120 film holder to start with.Ģ. Doesn't solve my need to scan 70mm 127, and 617 negatives as I can't find negative holders for these sizes. ![]() Shim up the negative holders by 0.33mm and use ScanTech SuperGlass™ ANTI NEWTON RING (ANR) Precision glass sheets to hold the 120 negatives flat. Epson must have had special tools to do this in a production mode. So how do I fix it? I suspect that there is some adjustment that the factory did to set the lens focus but I am not eager to open up the scanner and start turning screws blindly. The transparency scan focus point is set at 1.33mm. I think this is about as good as it will get. ![]()
