locating a transparency in a window of the template; passing a first light through a first aperture in the template during a first scan of the transparency; passing a second light through the first aperture in the template during a second scan of the transparency; and aligning a first electronic image from the first scan and a second electronic image from the second scan based on sensed light through the aperture. ### Claim 2 (depends on 1) The method of claim 1, wherein the first light and the second light are passed through a first transparent layer across the aperture. ### Claim 3 (depends on 2) The method of claim 2, wherein the transparent layer includes a first fiducial marking on the layer. ### Claim 4 (depends on 3) The method of claim 3, wherein the fiducial marking is printed upon the transparent layer. ### Claim 5 (depends on 1) The method of claim 1 further comprising: sensing light that has passed through an opening to identify the template. ### Claim 6 (depends on 1) The method of claim 1, wherein the transparency is selected from a group of transparencies consisting of a film negative strip, medium format film, large format film, a slide or combinations thereof. ### Claim 7 (depends on 1) The method of claim 1 further comprising: sensing an intensity of the first light that has passed through the first aperture; and determining a location of the first aperture based on the sensed intensity of the first light. ### Claim 8 (depends on 1) The method of claim 1, wherein the first light and the second light are from one or more same sources. ### Claim 9 (depends on 1) The method of claim 1, wherein the first light and the second light are from one or more different sources. ### Claim 10 (depends on 9) The method of claim 9, wherein the first light is visible light and wherein the second light is infrared light. ### Claim 11 (depends on 1) The method of claim 1, wherein the first light is a first visible light having a first wavelength peak and wherein the second light is a visible light having a second wavelength peak. ### Claim 12 (depends on 1) The method of claim 1 further comprising: passing the first light through a second aperture through the template during the first scan of the transparency; passing the second light through the second aperture through the template during the second scan of the transparency; and aligning the first electronic image from the first scan and the second electronic image from the second scan based on sensed light through the second aperture. ### Claim 13 (depends on 1) The method of claim 1, wherein the first light is a first visible light, wherein the second light is a second visible light distinct from the first light and wherein the method further comprises: passing a third infrared light through the first aperture in the template during a third scan of the transparency; and aligning a third electronic image from the third scan with the first electronic image and the second electronic image based on sensed light through the aperture. ### Claim 14 A system comprising: a scanner comprising: a scan bed; and a controller; and a template comprising: a body having a window configured to receive a transparency; and an aperture through the body configured to transmit light when the template is placed on the scan bed, wherein the controller is configured to align multiple scanned images using sensed light through the aperture. ### Claim 15 (depends on 14) The system of claim 14, wherein the template further includes a transparent layer across the aperture and a fiducial marking affixed on the transparent layer. ### Claim 16 (depends on 14) The system of claim 14, wherein the controller is configured to align the scanned images by determining a location of the aperture using a sensed intensity of light that has passed through the aperture. ### Claim 17 (depends on 14) The system of claim 14, wherein the scanner further comprises a first light source configured to emit visible light towards the transparency and a second light source configured to emit infrared light towards the transparency. ### Claim 18 (depends on 14) The system of claim 14, wherein the scanner further comprises one or more light sources configured to selectively emit distinct colors of visible light. ### Claim 19 A transparency template comprising: a body having a window configured to receive a transparency; an aperture through the body configured to transmit light when the template is placed on a scan bed; and a transparent layer across the aperture. ### Claim 20 (depends on 19) The transparency template of claim 19 further comprising a fiducial marking affixed on the layer.
