Instant image photography has been enjoying a comeback for some time now. Since 2015, instant camera sales have significantly increased. On the one hand, the advantage of polaroid photos is evident: immediately printed photos are instantly accessible, enabling photographers to immediately share their photos with others. On the other hand, polaroid photos wear out rather quickly, edges become frayed, tears and creases occur, photos become unattractive.
Fortunately, photo digitalization is quite simple. Digitalization preserves image quality, keeping the image intact and providing access to countless copies of the original image. It is also possible to restore blown out and even scratched images and then print them out in their new form. Whether working with black & white or color images, it is amazing to witness, the high-quality restoration of decade-old photos. A small tip: family photos can be scanned to create a beautiful picture album, an absolute eyecatcher and always a great present.
Now, let’s take a look at what to keep an eye on, especially when dealing with the high-quality scanning of photos, instant camera images and other reflective originals.
Working with high resolution, especially when scanning photos, is not always necessary. Photos usually have a resolution between 150 dpi and 600 dpi. For an image equal in both size and detail, a resolution of 300 dpi is recommended. If you want to print your images later, just enter the desired output size and SilverFast will automatically calculate the optimal required scanner resolution.
When increasing image size, it makes little sense to significantly increase image resolution as well. This is due to the fact that in most cases all image details are already recognized with 300 dpi. A resolution of 600 dpi is only required now-and-again by the odd exception. Ultimately, a higher resolution does not always guarantee increased image detail. A higher resolution means that the software is able to calculate additional image points that are not present in the original image. This is called interpolation. Interpolation can in turn decrease the sharpness of an image and should thus be avoided.
An image with a relatively low resolution is advantageous because of its quick processing time and comparatively small data size. This allows for the quick and effective scanning of large image archives.
