Image Histograms
- Image histograms tell a story
- the histogram exposed (i) – unimodal
- the histogram exposed (ii) – highlight-clipping
- the histogram exposed (iii) – bimodal
- the histogram exposed (iv) – multipeak-unimodal
- the histogram exposed (v) – indistinct
- the histogram exposed (vi) – multipeak
- the image histogram (i) – what is it?
- the image histogram (ii) – grayscale vs colour
- the image histogram (iii) – useful information
- the image histogram (iv) – shape
- the image histogram (v) – tone
- the image histogram (vi) – contrast and clipping
- the image histogram (vii) – log histograms
