If you think you might eventually need more copies of your 35mm slides, it is a good idea to order them all at the same time. Order multiple copies of your 35mm slides. Resizing in PhotoShop to 600 pixels by 900 pixels will still produce an excellent quality 35mm slide, with significant savings in file size.Ģ.
This is much higher than necessary for a 35mm slide. For example, an 8x12 inch photo scanned at 300 dpi will produce a digital image with a resolution of 2400 pixels by 3600 pixels. If your images are too high resolution, you can reduce the resolution of your images without losing quality by resizing them in an image editing program like PhotoShop. Creating images with unnecessarily high resolution, will needlessly increase the cost of your job without providing any increase in quality. The default resolution of scanners and digital cameras today often exceed the requirements for 35mm slides. In most cases, if you follow the guidelines below, you can reduce or eliminate the File Size Fee without sacrificing quality. In other words, you would be paying about 3 1/2 cents more per slide, in this example. Therefore, if you submit a 4.5 meg job containing 33 slides, the file size fee would be $1.20 (4.5 meg - 3.3 meg). The fee is $1/meg for excess beyond the allowance for that job. The same fee applies whether the files are uploaded over the Internet or submitted on disk or CD.įor example, if your job contains 33 slides, your allowance is 3.3 meg. For jobs consisting of more than one file, the job size is the sum of the sizes of the individual files. A job is defined as all the slides that are due at the same time, and may consist of one or more files.
That is, you are allowed 1 meg for every 10 slides, before you are charged the File Size Fee. The personnel time, the machine time, memory requirements, and the disk storage required to process large files containing high resolution images into 35mm slides are significantly greater than that required to process files of a smaller size.īecause of the increased time and cost of working with large files, we add a File Size Fee of $1/meg for jobs that exceed the allowance of 1 meg for every 10 slides. High resolution images cost more to process - $1/meg The total image size of the digital image in bytes is the total number of pixels times the number of bytes per pixel. The memory required to holdĪ digital image depends on the number of pixels and the number of bytes per pixel. Pixel to distinguish among 16 million colors. The color information may require oneīyte of memory per pixel to distinguish among 256 colors or 3 bytes per Of dpi and inches on a slide, we will use pixels rather than dpi to define the resolution of your image.Įach pixel is assigned a color. To convert dpi to pixels, you must know the dimension of your image in inches and multiply dpi times inches. Sometimes the resolution is defined as dots per inch or dpi. For example, an image might have a resolution of 900圆00, meaning it is 900 pixels wide and 600 pixels tall. The resolution is bestĭefined as how many pixels across and how many pixels down the image has. Of the image refers to how many pixels it contains. Creating digital images with unnecessarily high resolution, will needlessly increase the cost of your job without providing any significant increase in quality.ĭigital images consist of many dots or " pixels". The default resolution of scanners and digital cameras today often exceed the requirements for most 35mm slides. JPG, TIF, GIF, and BMP are the most common formats for digital images. For a more detailed discussion of the issues, continue reading below.ĭigital images are images such as you might obtain from scanning a photograph or using a digital camera. However, you should avoid paying dollars extra for needlessly large files (images much greater than 900圆00) that don't improve the quality of your 35mm slide. That may mean paying a few cents extra per slide for file size. In most cases a resolution of about 900 pixels by 600 pixels is sufficient. Resolution and Size for 35mm Slides from Digital Art, JPG, and PowerPoint Image Resolution & File Size (Back to IQ Imaging Home Page) Summary We recommend that you use the resolution you need to get the quality you need, but not any more than that.
