If you scan your own negatives then you will be very familiar with the problem of trying to keep them free from dust. If like me and you live in squalor, then you will often feel like you are fighting a losing battle, but an obvious discovery now helps me keep my negatives nice and clean and free from dust.
Really this tipster feels so obvious that I feel a bit silly suggesting it. In reality though it has saved me a huge amount of time and frustration and has allowed me to banish all thoughts of using Photoshop to just tidy up that little speck of dust that I think I should share it.
If you use a flatbed scanner to scan your negatives then they will have an inset in the lid of the scanner which normally covers the back lighting unit and provides a plane white background when scanning printed photos. When you scan film you have to remove the insert and it is this smooth, clean, white surface that I now prepare all my negatives on.
The insert is perfect for this job as not only is it easy to clean using a microfiber cloth or air blower, it also shows up the image on the film quite clearly. Now that I use this instead of doing it on my desk top or my computer keyboard, I hardly have any problems with dust at all.
