You can correct this with: > Retouch -> Sharpen Image. Thanks ! -- I tried unbending, but it seemed rather clumsy; clearly, I need to take more time to get the hang of how it works. > But: If you would like to make an exhibit, then you get > better image quality if you bring the negatives to an old-fashioned > photographer for direct enlargement on B&W photo paper. I may submit some of them to rail/transit journals for publication, but won't have a use for hardcopies nor did I know anyone still did that ... I checked all the apps in media-gfx , but very few are relevant : Graphicsmagick -- a long-ago fork of Imagemagick ; Digikam -- mb an alternative, but has 39 deps & 155 MB download ; Enblend -- removes dark/light line from .tiff's made eg by Hugin. Anyway, I have 3 apps to play with & will see where I get to. Thanks again for your very helpful advice & I HTH others. -- ========================,,============================================ SUPPORT ___________//___, Philip Webb ELECTRIC /] [] [] [] [] []| Cities Centre, University of Toronto TRANSIT `-O----------O---' purslowatchassdotutorontodotca
