Another area of questions is the scanning methods and statistics that we put on our products.
In short all of our film scanning is carried out at 300 dpi. To achieve the different sizes of scans we set a different target size so for example a 1.9mb JPEG scan has a target file size of 38" if opened in Photoshop and a 6.7mb JPEG file has a target size of 75" if opened in Photoshop. Both files scanned at 300dpi but with a larger overall target size giving you a much larger file.
Photoshop and other editing software unless programmed to do otherwise will always open the file at a size that the computer memory will cope with, bearing in mind that no one would probably want a print from a 35mm neg to 75 inches we then recommend handling the files as follows.
The first thing to change is the DPI setting back to 300 dpi, it will probably open at 72dpi. This is why we give you the two file properties for each service. Then whilst in the image size option set your image size to what you are going to be requiring, for example if you require a 10x8 image set the DPI to 300 and the image size to 8" high so cropping can be done after.
Please bear in mind that all black and white film types contain GRAIN, this is the silver particles that the film is made up from. The faster the film the larger the grain so this is not a scanning fault or something that has happened in processing this is the properties of the Black and White Film.
All Black and White film we receive is processed in Ilford ID11 developer, we process all film at 20 degrees Celsius. We have been using the same developer brand for the last 38 years and it is a tried and tested formula to suit all films in the market.
