Determining the correct resolution for your needs is an important step when planning to use our scanning service to convert your traditional media into digital format. Below you'll find some recommendation that will help you assess your needs. What is Resolution? The amount of detail captured with a scanner is determined by something called scanning resolution. Resolution is measured in dots per inch or DPI.
DPI means that a scanner will capture so many dots or pixels for every inch of area scanned. Click here for a more in depth explanation. What resolutions are available? With our film scanning service you have a choice of three resolutions: , , and DPI. Which resolution is right for me? This depends on your needs and what you wish to do with your scanned images. If you're looking to view your new digital images on a computer your needs will be different than someone who wants to create 11x14 prints.
If you're wanting to archive and preserve all the detail contained in your film or prints your choice of resolution might be different still. We'll discuss various needs below. Computer and video related use is not as demanding as printing or archiving, and allows for a lower scanning resolution. The chart below lists output resolutions of TVs and computer monitors.
Now lets compare the resolutions from the chart above to a film scan. The chart below lists the resulting output resolution of a standard 35mm slide or negative. If you compare a DPI film scan to the output resolutions of TVs and computer monitors you'll see that a DPI film scan is more than sufficient for viewing on your computer or television. Here's a quick cheat sheet: Slide 35mm Slide Approx.
But use DPI, and you'll get 24x36 digital images. But use DPI and you'll get 24x36 digital images. If so, you'll be safe using DPI. If you want scans as big as poster size 24x36 use DPI. They'll take longer, but you'll get better quality. Get help with your slide scanning project by telling me your challenges Which of these scanning troubles do you want to overcome? That's basically what the scanner is doing as well when it's using this digital Interpolated resolution.
All it's really doing is blowing up the pixels and cropping the image around it. The image quality doesn't get better — really only worse.
So, my suggestion to anyone is never to go beyond the optical resolution of your scanner. So at the highest, with the Epson V don't scan your prints, slides or negatives above dpi. But, even that is overkill and you will see not only a massively huge file size, but also too much grain when scanning film. Computers these days are fast enough to handle the file size, but the additional grain isn't so good.
I like to keep it simple and break people down into 2 categories. Those with basic goals, and those with advanced goals. If you are scanning your negatives to just have some nice pictures, but you don't really care about getting them perfect, or your computer is fairly old and you don't want large file sizes for example, then dpi is just fine.
This will make average people happy. If however, you really want to do it the right way — you really want to archive the best quality of the image that you possibly can so you can pass them down to your family someday, then I would recommend going with a dpi between dpi — dpi. If you try dpi and you feel there is too much grain, work your way down to dpi.
But, I wouldn't go any lower than if you really want to archive a high quality film scan. Since they are the source for many photos, you should scan 35mm slides and negatives at a high DPI. A standard scanning is DPI, while a high-quality resolution would be DPI, the maximum scanning resolution for 35mm film.
Digital scans of large negatives and transparencies at DPI for standard quality and DPI for high-quality will get the job done. When deciding on the best resolution for scanning photos, remember that a high DPI only really matters when projects require extreme detail, such as with archival projects.
Our digital photo scanning service will provide you with high-quality scans for any project or website. Cart 0. Sign In My Account.
