Image Scanning
This is the process of scanning a physical paper, film or bonded image to make a digital copy of it. The digital version can then be manipulated, enhanced or repaired and supplied as a digital image file or printed and prepared like any other photograph.
This usually requires getting the original media to me safely, to be scanned. See the guidelines relating to this on my site.
Scans can be performed to varying standards and at different resolutions depending on what you need.
Resolution
This is usually dependant on how much you intend enlarging an image, as the more you enlarge it the more any imperfections are emphasised and the more the dots (pixels) that make up the image become visible. An image containing around 240 - 300 dots per square inch (dpi) is usually good enough to print as a photograph on paper, while generally 96dpi-150dpi is normally reasonable to display online. As you enlarge an image, the dpi drops so you can over-enlarge images with lower dpi (or resolution).
Dust, scratches and artefacts
All photos get dirty with time and negative and slide film are especially prone to attracting dirt (the plastic holds a static charge) and can be easily scratched. The more you enlarge an image, the more these become obvious. The relevant sections will guide you as these can be minimised.
Please note:
While every effort is made to remove dust from film media, we cannot guarantee dust-free scanning. Media will be cleaned using non-contact pressurised air and digital methods are available to reduce the effect of dust.
