I'm starting to setup for scanning hundreds of my fathers old
photographs. He has a myriad of print sizes, color/BW, as well as some 120 negatives and I expect to have configuration files saved for each. It would be nice if Vuescan can: * Display the name of the configuration on the title bar * Somehow indicate that the configuration has changed - e.g. add "(Modified)" to the title bar. to remind me that I should save to a new configuration file. * Have an option to start Vuescan: - vuescan.ini - the last ini file manually loaded - a fixed ini filename * Allow fast change of configuration by dragging an INI file from explorer onto the Vuescan window. TIA bruceh |

All your requests make perfect sense to me.
May I add some ? - move the crop window around without changing its size. This could be done by clicking anywhere within it (away from the borders or from the Focus target) and dragging. Convenient when you want to keep the same file size. - there's no 'Generic' B&W film. I'm currently scanning Fuji Acros 100 and Fuji Neopan 400 and all the B&W predefined settings pretty much suck for those. At random I found a decent color one. - a harder one now: for films inserted in a strip reader, it's probably not too hard to set the [Frame Offset] automatically by looking at when there's actually something on the scanned line. Or have a right-click option on the preview with [Set Offset Here]. - And yet another change request for the UIR: the right side should be a set of inner windows. The classic ones that can be cascaded, tiled, overlaped... With auto resize for the scans, previews or histograms within. This way one can compare Scan and preview. Or act on the histogram while seeing the result. Alternatively the histograms could be in a pop-up window. Now a more general question. The focus is done on one point of the image, but recently I scanned slides that had a lot of curvature (probably due to poor mounts). The sides of the scans were completely out of focus. What's the best way to have the entire image in focus ? -- Guillaume Dargaud http://www.gdargaud.net/ "A printer consists of three main parts: the case, the jammed paper tray and the blinking red light" |

Unless you use a glass-carrier or you frame the film in a slideframe with (anti-Newton) glass, the film (which should be stored flat) will have some curl. If you scan a curled film, you should try and use the depth of field of the scanner optics. This usually means that you need to focus approximately at 50-60% from the Center to the Edge of your crop area. This assumes a convex film curl as seen from the scanner optics. Bart |

Thanks for the answer I know some slide projectors have (expensive) lenses that take the assumed curvature (usually only of a specific film like Kodachrome) into effect. I wondered if there were similar things built into some scanners. How much is the depth of field of a film scanner ? Is there a way to know ? Glass mounts, maybe but I've never liked them: way too much dust. I fought with it for years on my old B&W enlarger. It was impossible to keep dust-free. And the anti-newton looses a lot of definition. I assume there'd be the same problems with slides. Good normal mounts can help alleviate the problem but the shop mounted all my last batch of rolls with cheap mounts (the kind that inserts sideways). -- Guillaume Dargaud http://www.gdargaud.net/ "— Dad, I decided to quit college and take up a life of crime. — That's nice son, government or politics ?" |

Only by trial and error, but VueScan can help with that. 1. You can determine the depth of field needed, by setting the focusing to Manual. This will reveal the current setting. Now drag the focus indicator to a corner of the crop area and (for Windows) hit CTRL U or use the menu Scanner|Focus, and record the focus setting. Repeat for the center of the crop area. Now you probably know the maximum depth difference. Roughly half of it is what needs to be above/below the focus plane. 2. To save some scanning time, choose a very small crop area, and set the Crop|Preview area to "Crop box" (don't forget to set it to default again when you're done). Focus on a (grainy) piece of film with Preview resolution set to Full (or the maximum for your scanner). Now you can type values in the Manual focus text box, do another Preview, and see how much difference up and down from best focus you can tolerate (for your final output size !). Make sure that the film didn't change shape while heating-up by doing another forced auto focus (you should get approximately the same value as you did earlier). Bart |

No problems with curved surfaces either. I suspect its optics were more expensive (at that time, the scanner cost almost twice as much as what a DSE 5400 costs now) and nowadays the combination of AF with cheaper optics seems to be favored by manufacturers. BTW, Nikon scanners from the same era as the DSS 2800 were already equipped with AF. -- Wilfred van der Vegte. Replace 'invalid' by my first name to reply by e-mail |
