Frequently Asked Questions
What is the optimal resolution for printing posters larger than 8”x10”?
The minimum resolution for an 8”x10” printed at 250 dpi (Dots per inch) would be 2000 x 2500 pixels (5MP) with a file size of approximately 3.5MB. To print larger, a higher resolution would be required. A 24MP image (4000×6000) can print as large as 16”x24” at 250 dpi with file sizes of up to 10-15MB.
I want to have an enlargement made at a commercial lab. What can I do to ensure the print will look the best?
Use photo editing software such as PhotoShop or Lightroom to resize and sharpen the photo, adjust the photo’s colour profile, and ensure your photo is at the right resolution for the printer you will be using.
What are the recommended file types I can work with?
In most cases, JPEG image files are all you need to print images, from regular-sized photos up to poster format.
- JPEG: Most cameras capture and record .jpg (JPEG) files. This is the most common file type.
- RAW: Many cameras can also record RAW image files. These files can contain additional image information. However, the files are quite large, and require a computer and software to be able to view and process to JPEG or TIFF.
- TIFF: These files are larger and contain more data. They’re used to create large photo prints — bigger than the size of a poster. Typically TIFF images are converted from RAW.
- HEIC: Newer iOS devices use a “High Efficiency” file format. While this does reduce the image file size, there are not yet many options for viewing HEIC files
What software can I use to view and edit my photos?
The software you use depends on how experienced you are with editing photos.
Beginners: The software included with your Windows or Mac operating system
Mid range: Adobe Elements
Experienced: Adobe PhotoShop, LightRoom, ACDSee, Capture One
How do I transfer photos from my camera to my computer?
There are several options for transferring photos from your digital camera:
- Direct camera connection using your camera’s USB cable: Your digital camera may have included a USB cable that allows you to easily download photos to your computer. Make sure your camera’s batteries are charged.
- Using your computer’s built-in card reader or a USB card reader: This replaces the need to connect the camera directly to your computer. Insert your memory card directly into the card reader on your computer.
- Wi-Fi/Bluetooth: Some digital cameras can transfer images via WiFi or Bluetooth. Check with your camera manufacturer to find out more.
- Mobile devices: Most cameras can transfer images wirelessly to iOS and Android devices. Once the photos are on your mobile device, you can transfer them directly to your computer, or transfer them from cloud storage to your computer.
