Digital equipment has become so much a part of the world of photography that some individuals may wonder was there really a time when it was not. That along with the treasures of film-era slides and negatives that exist make digital slide scanners a practical investment for a number of professional photographers and avid novices. There are some key aspects to choosing the best slide scanner for you though. The result is selecting a balance between these key elements.
Distinction
The first step is to realize that there is a distinction of quality among slide scanners. There are a number of slide scanners that are considered entry level by many. These scanners are designed to provide a low-quality scanner at a very low price. In most cases the avid novice will prefer not to use these scanners. Those that perform professional quality photography work should know that these are not the best slide scanner for them.
A basic rule is not to consider any scanner that supplies less than a 2700 DPI image. This is a general minimum. There may be some instances when you can work with less. The case of web thumbnails is an example, but likely your source image for those thumbnails will be around 2700 DPI for a professional image.
Quality
This brings us to quality. That minimum rule of 2700 DPI is a good start to a measure of quality. Another factor when considering the best slide scanner is to consider the way that it works. A number of flatbed scanners may claim that they can scan slides. You may be able to capture an image that is suitable for a web thumbnail using this method, but there is far more available.
Quality slide scanners allow for individual focusing. These capabilities allow you to create images that appear as you intend them to, and are generally only available on dedicated slide scanners. Some of the fine-tuning can be done using software now. Some programs allow for phenomenal adjustment that may be able to compensate for your scanners lack of ability.
Speed
This is a consideration when choosing the best slide scanner for you. When achieving the higher DPI resolutions some machines may scan considerably slower. It is important to be aware of the amount of slow-down that you may experience when you capture images at higher DPI's. Directly related, you should estimate how many slides you plan to scan. This will be helpful in determining how fast the scanner needs to scan for you to complete your tasks in a suitable time-frame.
Accessories and Preferences
Ultimately, the above will direct you to which class of slide scanner you need. Deciding which particular scanner is the best slide scanner for you may fall squarely on the details of accessories and preferences. You can find specialized features in some slide scanners like scanning directly to a memory card, or other output formats. In addition, the software that you receive will vary from scanner to scanner. Lastly, many of the top names in electronics and photography produce slide scanners. If you prefer a particular brand you may want to find out what they offer before making your choice.
