If you are looking to buy a film slide scanner, you will find hundreds of different brands with different products in the market. The whole process can be quiet confusing unless you know what you are looking for. To make matters simpler, you should list down a few features that you need to be careful about in the film and slide scanner that you are going to buy. The main feature of any film slide scanner is the dpi of the images that it produces. It is a suitable yardstick to measure the effectiveness of a slide film scanner. You should select a scanner with a suitable dpi rating according to your use. If you’re a professional photographer wanting top quality images in your computer, go for a scanner with a high dpi rating when it converts 35 mm slides into digital form.
Most people believe that if they get a scanner with a very high dpi like 1200, they will get the best quality images. However, experts are of the opinion that most original photographs don’t have a resolution of more than 200 dpi which is why you shouldn’t waste money on scanners with a very high dpi rating like 600 and 1200. 300 dpi is a good enough rating and anything more than that isn’t really helpful. The second thing that you need to look for in the scanner is the processing time that it takes in order to convert slides into digital form.
Most modern scanners don’t take more than a second to do the job which can come in quiet handy in offices and workplaces where time is precious. In order to operate a scanner from your pc, software is required, However, some scanners don’t require a software to be installed in your computer and can connect directly. This is a feature that you should look for in the scanner. Rather than having to install software each time you operate the scanner on a different laptop or pc, go for a scanner which has inbuilt software and can connect instantly.
Establishing a connection between a computer and the film slide scanners can become a problem for users. This is the reason that some companies have introduced a USB Interface in the scanner which means the pc and the scanner can be connected via a USB port. The USB interface is much more convenient than the traditionally difficult to connect SCSI port. Brands like Hewlett Packard have introduced USB ports. This can help you save on time. Film slide scanners should have an automatic exposure control and color balance mechanism so that the scanned image is of high quality without any color imbalances.
