Claims
- 1. A method of developing a latent image on an exposed photographic element, comprising:
(a) applying a developer solution to said photographic element; and (b) scanning said photographic element with at least two different wavelength bands of electromagnetic radiation while said latent image is developing.
- 2. The method of claim 1, wherein the at least two wavelength bands include visible and infrared light.
- 3. The method of claim 1, wherein at least one wavelength band comprises infrared light.
- 4. The method of claim 3, wherein said scanning step comprises:
directing light of said first wavelength at a first surface of said photographic element; directing light of said second wavelength at a second surface of said photographic element; detecting light of said first wavelength reflected away from said first surface; and detecting light of said second wavelength transmitted through said second surface.
- 5. The method of claim 4, wherein said second wavelength includes infrared light.
- 6. The method of claim 1, wherein light of a first wavelength and light of a second wavelength are simultaneously directed at said photographic element.
- 7. The method of claim 1, wherein said scanning is performed at a first predetermined time after application of said developer solution.
- 8. The method of claim 1, wherein said scanning is performed at multiple predetermined times after application of said developer solution.
- 9. A method of electronically developing a latent image on exposed film, comprising:
applying a developer solution to the film; and scanning said coated film simultaneously with light of at least two different wavelengths.
- 10. The method of claim 9, wherein said scanning step comprises directing light of a first wavelength at a first surface of said film, directing light of a second wavelength at a second surface of said film, and detecting light reflected away from said first and second surfaces and light transmitted through said film.
- 11. The method of claim 9, wherein said film is scanned at a multiple times during development.
- 12. The method of claim 9, wherein said light comprises infrared light.
- 13. The method of claim 9, wherein said light comprises visible light.
- 14. The method of claim 13, wherein said visible light comprises the wavelengths of red and green light.
- 15. The method of claim 13, wherein said light also comprises infrared light.
- 16. The method of claim 9, wherein said light comprises red, green and blue light.
- 17. The method of claim 9, wherein said light comprises red, blue and infrared light.
- 18. An improved digital film scanning apparatus for use in electronic film development, the apparatus comprising:
a first source of electromagnetic radiation configured for directing radiation of a first wavelength at film; a second source of electromagnetic radiation configured for directing radiation of a second wavelength at film; a plurality of first optical sensors which are responsive to radiation of said first wavelength and are substantially unresponsive to radiation of said second wavelength; and a plurality of second optical sensors which are responsive to radiation of said second wavelength and are substantially unresponsive to radiation of said first wavelength.
- 19. The improved digital scanning apparatus of claim 18, further comprising a developer supply station configured for applying a developer solution to said film.
- 20. The improved digital scanning apparatus of claim 18, wherein said first wavelength is within the visible portion of the electromagnetic spectrum, and said second wavelength is within the infrared portion of the electromagnetic spectrum.
- 21. The improved digital scanning apparatus of claim 18, wherein said first wavelength comprises the colors red, green and blue light, and said second wavelength comprises infrared light.
- 22. The improved digital scanning apparatus of claim 18, wherein said first and second optical sensors measure radiation of said first and second wavelength transmitted through the film.
