1. Seeing the Invisible Unveiling Hidden Details through Advanced Image Acquisition Techniques

2. The Cost of Correction Trying to enhance a poorly shot photo in Photoshop—significant effort with limited results.

3. Two Concepts we’re going to cover

4. Lens Aperture The Quest for Clarity

5. The Surge of High-Megapixel Cameras

6. 200MP The fine print: 0.56㎛ pixels, the smallest pixels in the industry, in a 1/1.4” optical format. 1

7. The Resolution-Sensitivity Trade-off Source: Princeton Instruments

8. Aperture: Improving your focus

9. Diffraction

10. Basics of Lens and Diffraction

11. Diffraction Pattern: Airy Disc

12. Effect of Aperture size on Image ‘sharpness’

13. Diffraction Effect when disk size > pixel size

14. DoF (Depth of Focus)?

15. Circle of Confusion

16. Aperture and Effect of DoF

17. Use an aperture to ensure Airy disk size AND CoC is smaller than the pixel size

18. Concept2: Multispectral Imaging The Spectrum Beyond Sight

19. Expanding Vision: Beyond RGB

20. The Multidimensional Image

21. Spectral Cube

22. Seeing the Unseen: Material Identification

23. Multispectral vs Hyperspectral Imaging Source: Edmund Optics

24. Spot the Difference: Almonds and Shells RGB, multispectral (28 bands), and hyperspectral (224 bands) images of almonds and shells (green is almond and blue is shell).
