![]() For several print appplications of medium formats (not for archival storage) a lower resolution of 2800 dpi may be enough. However those image files are very large and thus can only be processed with fast computers. So for archival storage of medium format images the highest resolution of 4000dpi in TIF format is recommended. Since medium format films are usually being exposed with very high-grade camera-lens-combinations the film material provides a resolution of 4000 dpi. ![]() The image format of the largest medium format 6x9 is sized 56 x 85 mm - resulting in an image area of 47,6 cm², thus almost 8 times bigger than the image area of a 35mm film format. With the medium format 6x8 the image has a format of 56 x 75 mm, so the image area is sized 42 cm². The image format of an 6x7 frame is sized 56 x 69 mm which is 38,6 cm². The square medium format 6圆 provides an image format sized 56 x 56 mm which corresponds a film area sized 31,4 cm². The smallest medium format 6x4.5 provides an image format of 56 x 42 mm, which comes up 23,5 cm² film area, thus almost 3 times the size of an 35mm frame. For the long side of the film (in rolling direction) there are different formats: 6x4.5, 6圆, 6x7, 6x8 and 6x9. Medium format roll films have a fixed side length of 6cm with a usable film heigth of 56mm. In order to make A4 sized print outs a resolution of 4000 dpi is necessary. The lowest resolution of 2000dpi provides only 2,7 Megapixel, thus much less than current beginner's digital cameras. For APS films we recommend a resolution of 2800dpi or 4000dpi. Accordingly the dimensions, pixel amounts and file sizes of the APS format are smaller compared to the 35mm format. Thus a film area of 5,04 cm² results, which is about 40% smaller than the 35mm format. 35mm slides or negatives 24x36Ģ000 dpi, TIF format, 48 Bit colour depthĢ800 dpi, TIF format, 48 Bit colour depthĤ000 dpi, TIF format, 48 Bit colour depthĪPS films have an image format of 16,7 x 30,2 mm. We recommend the highest resolution of 4000dpi for film material exposed with a top quality SLR/lens. The medium resolution of 2800dpi contains 10 Megapixel and corresponds very good digital camera format. The lowest resolution of 2000dpi is not suitable for archival storage because the resulting image file only contains 5 Megapixel. We offer digitalisation of 35mm slides or negatives with 2000 dpi, 2800 dpi and 4000 dpi resolution. 35mm filmsģ5mm films have an image format of 24 x 36 mm. An image with large consistently coloured areas, for example blue sky or white snow, can be compressed much smaller than an image with a large colourful crowd and lots of details. The size of JPG files depends on the image content. The exact amount of pixels results from the scan area - it is larger if the image is not automatically cropped. All specifications are approximate values which differ slightly from scan to scan. The following tables give a rough overview about the resulting image and file sizes for digitalisation.
