Digital camera files as small as 640 pixels by 480 pixels may give you an acceptable 35mm slide depending on your subject matter, but larger files will always produce better slides than smaller files. However, do not start with a small image from your digital camera and use software such as Photoshop, PhotoDeluxe, or PhotoPaint to simply enlarge it (retouching it is OK). For the best quality 35mm slides from your digital camera, set the camera to the largest file size and least compression possible. However, keeping that in mind, smaller files do transmit by e-mail or FTP much quicker, and our software will automatically enlarge the image from your camera to fit the slide mount. You may send either vertical or horizontal images (either portrait or landscape) and we will fill the slide mouint as much as possible. JPEG files are good, as are TIFF and RGB Photoshop files.
Photographic Specialties is no longer producing slides and transparencies. I have been self-employed for 35 years, but looking forward to retirement since my wife died five years ago. With the decline of conventional photography and the recent recession, the availability of film and chemicals as well as the volume of work has declined to such an extent that it is no longer possible to have fresh chemicals to develop film. I hope that if you still need conventional slides and transparencies, you will be able to find someone who can produce them for you. Thank you for your orders over the years.
