Q6: What is DPI? What’s the fuss over high resolution? 3000 DPI, 600 DPI?
|
|
Seeing is believing. Before you read any further, check out our quality page: Do it Once, Do it Right, At high Quality. DPI stands for dots per inch; it is a measure of the resolution, accuracy, sharpness and clarity of your scanned picture. Up to a certain point, the higher the DPI resolution, the better the image; but this also takes longer to scan and process. With higher resolution, you can enlarge your image to larger size. With ScanCafe's DPI resolution, you can enlarge a paper photo to twice its original size, and print a negative/slide to 20x30 inches.
Based on millions of scans, we find that the optimal DPI levels are: 600 DPI for paper photo and 3000 DPI for slides and negatives.
Most scanning services charge extra for what is our standard resolution. Your pictures deserve a professional level of scanning and processing.
When shopping for a scanning service, make sure you compare price at equivalent resolution and with the equivalent level of image processing. ScanCafe service is all-inclusive: high resolution scanning, Kodak digital ICE and Photoshop manual processing.
For special purpose applications, such as very large print enlargements, we offer a higher resolution scanning option. If you would like to have your paper photos scanned at 1200 DPI, or your slides and negatives scanned at 4000 DPI, please be sure to order “Pro Resolution” on the online order form. |

Q29: How big can I enlarge/reprint my pictures?
|
|
Printing and enlarging photos can be as much art as science, as acceptable quality can sometimes depend on the use, or even the image itself.
But a good rule of thumb is to think about photo quality printing, which most in the printing industry define as around 300 pixels per inch. (Books and magazines typically print photos to this standard).
At that standard, you should be able to enlarge any paper photo we scan at 600dpi by 2X (i.e., a 4"x6" could increase to 8" x 6") without any decrease in sharpness.
Slides and negatives, however, can be printed much larger, thanks to their naturally higher resolution. At our standard scanning resolution of 3000dpi, a 35mm negative could be printed, photo quality, at 9" x 13", roughly.
You do not always need to print at photo quality, however. If, for example, your print is going to be seen from a distance, you can print much larger. In testing, for example, we've printed 35mm negatives to 20" x 30" and been very pleased with the results.
If you are interested in making a poster or other large print that is going to viewed up close, we'd suggest that you use our Pro Resolution feature, which scans paper photos at 1200dpi and 35mm negatives and slides at 4000dpi. That would enable, in the case of negatives, an approximately 12" x 18" print at photo quality. We'd also suggest you have us deliver the scans to you in TIFF format, since with our jpgs there is a slight amount of compression. Both of these features cost just a few cents extra, so they will be well worth it when you make a very large print. |

Q40: My order is large or heavy, can I split my order into two separate boxes?
|
|
Unfortunately the answer is no, for the following reason – the UPS label that is automatically generated has a single tracking ID for a single package. If you were to print two copies of this label, then UPS would only track one of the boxes. If they were to misplace the second box, but deliver the first box, then you would have no proof of this as the delivery info would have followed the first box. Additionally, ScanCafe would have no idea that two boxes were coming. You can remedy this by either getting your order into a larger single box (large boxes suitable for shipping can be found at the UPS Store, FedEx/Kinkos, or any office supply store such as Staples or Office Depot) or by actually placing two orders on the site and applying a single label to each box. You could then track each box separately all the way through the process. If you do decide to place a heavy order into a single box (more than 10 pounds), then we highly recommend you take the order to a UPS Store or a Kinkos so that they can help you prepare the box for shipment to insure that the packing method used is sufficient. Please feel free to contact us with any additional questions on this topic at admin@scancafe.com or at 866-745-0392. One last piece of advice - if you look at the bottom of any shipping box, you will see the amount of weight that that box is rated for in both pounds and burst capacity. |

Q44: Are my gift recipient’s images safe with ScanCafe?
|
|
Yes, they are. Your Gift Box will be tracked from door to door using our integrated UPS tracking system, and handled according to the same procedures that have allowed us to successfully scan over 41 million images. While at our scanning facility, your recipient’s images will be under 24x7 monitoring in a controlled-access, climate-controlled environment, and handled with our usual white glove treatment by trained technicians. In addition, all Gift Box orders are covered by our standard $1,000 handling guarantee, which promises that if your recipient’s gift box is lost while in the possession of ScanCafe, we will compensate your recipient up to $1,000 in cash and a year of free scanning services. The gift box must be packed in accordance with ScanCafe packaging instructions in order to be covered by our guarantee. |

Q46: Can I buy this for myself?
|
|
Yes, you can. However, you will probably find that our regular scanning service will make more sense, for two reasons. First, with our regular scanning service, you send us your slides, negatives, and photos, and we charge you precisely for what you send. It’s hard to say the same thing for the Gift Box, since it’s hard to say how many images you will be able to fit into it, in advance. Second, with our regular service, you’ll have a chance to review your images, and delete the ones that you don’t want, up to 50% of your order. As the Gift Box is really intended for a gift to someone who’s not so comfortable with the internet, there is no review opportunity—once we scan the box’s contents, we return the originals and the scans immediately. |

Q73: Which dpi should I choose for photo scanning?
|
|
The short answer is that higher dpi leads to higher quality, and our belief is do it right the first time and you'll never have to worry about it again. You can scan photos at a lower dpi and pay less, but the photo scan quality will not be as good and there usually are zero post scan services such as color correction and cropping - so be wary. At ScanCafe, we want you to have the highest quality so we scan at 600 dpi. You can see some specific examples on our quality comparison page.
Is 300 dpi just as good? Unfortunately, it is not. You can take a look at our side to side quality comparisons of 150dpi, 300dpi, and 600dpi. 600dpi simply picks up more information from the print. Furthermore, you can scan and print a 4x6 photo at 300 dpi, but you will never be able to enlarge the print at a later time to a 5x7, for example. As technology gets better, you'll find more value in the 600 dpi. Again, when it comes to photo scanning, do it right the first time, and you'll never have to do it again.
Furthermore, if you want to get the most out of post-scan services like photo restoration, you will definitely want to scan your photo at 600dpi. |

Q140: Do you scan Medium Format negatives?
|
|
Yes, we do. Most commonly, this format comes from 120 or 220 film. But for us, really, it's any format that is larger than traditional 35mm and smaller than 4" x 5", which is where our Large Format category begins.
Common Medium Format frame sizes that we scan are 6x6cm, 6x4.5cm (sometimes called "645"), 6x7cm, and 6x9cm.
We scan these on our Nikon 9000 EDs. Also, for black & white medium format negatives, we apply our patent-pending wet mount process that virtually eliminates the scratches that affect so many old black & white negatives.
We scan, by default, at 3000 dpi. The file sizes created for each medium format scan depend on the exact size of the frame submitted, but are in general at least 7MB and as much as 25MB.
That translates to a recommended printing size range of up to 33 x 22 inches. At that size, the print would be rendered at effectively 300 pixels per inch, a common printing standard for up-close viewing. (If the print is intended to be viewed from many, many feet away, you might be able to print larger with no noticeable defects).
We can scan Medium Format slides if they are color, but we currently cannot scan medium format slides if they black & white, as they are incompatible with our wet mount process. |

Q141: Do you scan Large Format negatives (or positives)?
|
|
Yes, we scan both positives and negatives in Large Format.
We are very proud to offer Large Format scanning at an outstanding price for our professional photographer customers. There is a very rich tradition of Large Format photography that we're excited to help preserve.
For frame sizes of 4"x5" or even 4"x6", we charge one price, and for frame sizes of 8"x10" we charge a bit more, due to the sharp increase in scanning time.
We perform these scans on dedicated Epson 10000 XL's at 3000 dpi, which creates some very large files suitable for a wide range of uses. A 4" x 5" Large Format scan from us will be about 50 MB in size, and suitable for 36" x 46" prints. Similarly, an 8" x 10" Large Format scan from us will be about 200MB in file size and suitable for prints intended for up-close viewing all the way up to 75" x 96".
We do not currently scan Black & White Large Format because our patent-pending wet mount process, designed to virtually eliminate scratches, is not available for Large Format yet. However, if you believe scratches will not be an issue for your Black & White Large Format negatives or positives, contact us and we'll make arrangements. |
