Important Information:
Digital cameras take photos of a different length to height ratio compared to that of traditional film cameras.
Traditional film cameras take photos that fit a 3:2 print ratio. Typically 6x4inch or 10x15cm. Digital cameras on the other hand, take photos that fit a 4:3 ratio originally conceptualised from your computer monitor (640x480, 800x600). A 4:3 ratio does not fit standard traditional film print sizes. A print from a digital camera will be 6x4.5" or 11.5x15cm.
The most obvious problem is that a 6x4.5" photo will not fit into a photo album pocket designed for 6x4" prints.
To overcome this, we can print your photo onto a 6x4" piece of paper (commonly, in the digital imaging industry, known as a canvas). We can do this either by cropping the top and bottom of your image or by printing your image fully at 5x3.75" on the 6x4" canvas, thus producing white borders.
NOTE: Borders are uneven with standard border width top and bottom and approximately twice standard border width on either end.
The simplest way around this problem is have us print your image full frame on 6x4.5" paper and put them into a drymount album.
