| Since I now manage to get Tame/2 to work with my scanner I made some test on scanning. First issue that I figured out is that Tame/2 has a limit on viewing files larger than 85mb. The file I scanned turned out to be 515mb and even pmView gave some trouble to open it, well it crashed actually giving following message: 10-19-2003 16:40:40 SYS3175 PID 005a TID 0004 Slot 00ab PMVIEW.EXE 0001:0003f828 My is this limit within pmView or actually OS2? |

| Kim, I do not know if your using the latest version 3.02 of PMView. I do not think that 500 Mb is a limit of either OS/2 or PMView... I agree that the files are big but should work... Else report your problem with PMView on the PMView list. With kind regards, Henk/2 |

I'm using version 2.32 so I guess that I should give it a try with the 3.02 version. But I would then have to upgrade and haven't really found any reason for myself to upgrade, yet Well, have to check a little more then. |

No, Tame (0.9.8) has no limit to show files >85MB, the limitation lies within tifproc.dll from OS/2, so only showing the files in Lighttable folder is disabled. >The file I scanned turned out to be 515mb and even pmView gave some >trouble to open it, well it crashed actually giving following message: Regardless if there is a bug in PmView or not, scanning such big files tells primarily one: The user hasn't understood how scanning works. For all unscaled purposes 300 DPI (~25MB picture size) are more than satiesfying. All higher resolutions are only (and really only then) needed if you want to scale a smaller picture (e.g. for scaling a 24x36 slide to DIN A4 you need 3200 DPI) But if you want to discover limitations furthermore: Simply try to print such a big 500MB picture (but please do a complete backup of your system before, otherwise you'll damn the day you've tried that. |

| I agree that there usually doesn't make any use to scan papper original over 300dpi. But if you're working with negativ you might want turn up the resolution. As well, for me I'm working (as for a hobby) with large images that I set together and I usually want to use uncompressed format to keep the quality and then have it developed at photo studio or printed out as poster. |

Only some hints: For printing in photo-quality 300DPI scans are more than enough (and you need a really good printer to get that printed correctly). DPI for scanners and for printers are something completly different. The only exception is: if you scan pictures from magazines/newspapers which already have a raster. To avoid moireé you should better scan in 600DPI and afterwards downsize it to 300DPI (and may try some filterings before downsizing) |
