Sky-Pix FAQ’s And Additional Notes

Question or Topic
Deciding which package is right for you
Do I want a Photo Print or a Digital Image?
Photo Prints:
Photo prints are intended for file, reference and display purposes and are not to be scanned, copied or reproduced without express permission from Sky-Pix.

Photo prints are available in 8x10 to mural sizes from stock images, Custom and Progressive Pix packages (one 8x10 is included with any Progressive shoot)
Digital Packages:
All digital packages include lifetime reproduction rights. Digital images are available in three tiers at different resolutions.

Digital images are cropped to your specifications and color corrected for optimal reproduction for print or web.

What is a "mural size" print?
Mural size prints refer to prints larger than 16x20 inches. A full frame 120 negative, scanned at highest resolution, can produce prints as large as 5x6 FEET.
What is a Tier #1 Digital image?
Tier #1 images are ideal for emailing, publishing on the web, putting into word documents and reports.

These images are delivered to you via email in a 4x5 format at 133ppi and include lifetime reproduction rights.
What is a Tier #2 Digital image?
Tier #2 images are versatile allowing print quality resolutions for printing in magazines, brochures, and other print ads. View images on your computer screen and edit them for your planning needs.

These images are delivered to you via email in an 8x10 format at 320ppi (approximately 8.5x11 at 300ppi) Tier #2 images include lifetime reproduction rights. Tier #1 images are also delivered as part of these packages.
What is a Tier #3 Digital image?
Tier #3 images are intended to cover all printing and reproduction needs. These images well exceed the specifications of the previous two tiers, enabling you to zoom in and see fine details of your photo(s), directly on your computer screen.

These images are delivered to you on Compact Disc, in a 2.1x2.8 inch format at 2,000ppi (approximate 30x40 at 150ppi) Tier #3 packages include Tier #1 and Tier #2 images as well as lifetime reproduction rights.
What do I do with digital files sent to my email?
Only tier #1 & Tier #2 images are sent via email. When you receive your email, you should save the attached photo(s) to a file folder on your computer or one on your network.

If you need to edit your file, we strongly recommend that you make a master file, using the "Save As" command, then selecting a file format that does not degrade the image, such as your application's native format (.psd - in the case of PhotoShop) or in "lossless" formats such as: .tif or .png. You can read more in our File Formats section of this page.

We also recommend that you make a back-up of your file and store it in a safe location.
Can I just scan prints myself?
Photo prints from Sky-Pix do not include reproduction rights or marketing releases. Scanning prints is a violation of our copyright, unless we have granted written permission to do so.
Understanding Copyrights
Copyright laws that protect photographers fall into a category of "Intelectual Property", as it does for all creative works. Simply put; the creator of an image is the copyright holder.

Print Sizes And Cropping Info
Proportional print dimensions
Not all standard print dimensions will scale proportionately. For example a 30x40 print, when reduced to 8”, will have the opposite dimension of 10.667”. This means that cropping of the image will occur when making an 8x10.
Why are my file sizes different, even though they are the same dimensions and resolution?
It is common for the storage size of image files to be different from one another, even though their measurements and resolution are the same (for example: you have two 4x5 digital files @ 133ppi yet one is 321k, the other is 379k)

The cause of this is in the way computers save pixel information and the number of colors in the image itself. Different colors are displayed by stacking pixels (short for picture element) in different orders to produce the necessary color. This causes more pixels to be used to display wide ranges of color which requires more disk space to store the file and more memory for an application to show it.

The important thing to consider is that the file's dimensions and resolution determine the requirement for your screen or print output, not the storage size of the file.

File Formats
Some notes about file formats
The primary file formats we use are JPEG, TIFF and PDF. JPEG (.jpg) files are used for any file that we will email to you. TIFF (.tif) files are used for printing as are PDF’s (.pdf), both are usually too large for downloading or uploading over the Internet. Please see additional notes on each format.
What is JPEG compression?
JPEG is a “lossy” compression format and is the abbreviation for the group who developed it: Joint Photographic Experts Group. JPEG is “lossy” because it divides images into blocks of pixel information, calculates the ranges into curves, then throws away insignificant curves depending on the quality setting used, the lower the quality, the more information is thrown away.
Why should I use JPEG compression?
JPEG is an excellent compression method for photographs and can reduce file sizes substantially. This is critical on web pages or any time there is a file transfer over the Internet.
When should I use JPEG images?
You should use JPEG files for web pages and emailing only. For print you will need one of the following formats: TIFF, EPS or PDF.
How should I work with my JPEG Images?
Any JPEG file you receive should be saved into a lossless format like TIFF or Photoshop’s native PSD. JPEG is a “lossy” format, meaning that: every time you re-save the image as a JPEG, it is re-compressed and the quality will degrade. Please do not re-save as a JPEG until you have the image sized the way you need it.
What is GIF file format?
GIF is Graphics Interchange Format, as the name implies, it is intended for use with graphics to be displayed on the Internet. This compression method is excellent for large areas of the same color but not suitable for subtle gradations of color such as in photographs. GIF is lossless to the degree that if re-saved, the compression does not throw out any additional information. It will however reduce the color range of a photo to 256 colors. You would only use this compression if you are combining your photo with graphics having large blocks of color such as bold lettering or logos.
What is TIFF file format?
TIFF stands for Tagged Image File Format and is usually the default format for scanners. This is the preferred format to work with because it retains all raw image data with no loss or compression. These files are often large in size depending on the dimensions and resolution of the file and are not suitable for file transfer over the Internet.
What is PDF file format?
PDF stands for Portable Document Format and was developed by Adobe Systems to create files that can be read by any computer platform (Windows, Macintosh, Linux, etc.) All that is needed to view or print a PDF is Adobe Acrobat Reader, which can be downloaded for free from Adobe’s web site:
Why would I need a PDF file?
PDF’s are used by some service bureaus especially Kinko’s. If you take any other file format to Kinko’s (even TIFF or EPS), you will be charged a conversion fee. If you are receiving a high resolution file from us on CD and plan on having Kinko’s produce your print, please let us know so we can save your file appropriately and save you this expense.

Some Notes About Image Resolution
Print Resolution
Print resolution depends on output size and the device that the image will be printed on. Industry standards are set to 300 ppi (pixels per inch) for sizes up to 11x17. Everything larger than 11x17 is printable at 150 ppi. The files we supply to you will meet or exceed these standards.
Web or Screen Resolution
Standard web resolution is 72 ppi (pixels per inch). Most computer monitors display at this resolution although some more expensive displays will preview images at 96 ppi. We supply you with web images at 133 ppi, allowing you to crop or re-size the image as needed, without any loss in image quality for the final image.
