Exercise 39 Contrast and Shadow Fill. Part II

This is the second part of the exercise -- replace the white card with aluminium card. I separate this from the first part because the conclusion here is different and these set of images should be viewed without those in the first part.


The light is positioned on the right side of the screen, with a softbox. I try to do a better job in fixing the tiger toy this time and shoot slightly tighter (still some empty space at the top, but the eyes is at 1/3 level). There is also catch light on the left.


Same as last time, I will start with my observation first:


1) I cannot see the difference between produced by the dull and shiny surface of Aluminium foil. The brightness is almost the same on the left side at both 10 and 20 cm. However, the catch light on the left eye is more concentrate with the shiny Aluminium. The dull side is more diverse (larger area, but seem weaker)


It is either there is little difference, or the co-corp Aluminium foil is not shiny enough to differentiate itself from the dull side.


2) The brightness on the left side of order of strength will be: Dull/Shiny > Crumbled side > white card. It tells me that an Aluminium foil is a more powerful reflector than the white card.


Here is the set of images:


1) No reflector






2) White card at about 10cm away on the left


3) Dull side of the Aluminium foil at 10 cm away on the left


4) Shiny side of the Aluminium foil at 10 cm away on the left


5) Crumbled Aluminium foil at 10 cm away on the left



6) White card at about 20cm away on the left


7) Dull side of the Aluminium foil at 20 cm away on the left


8) Shiny side of the Aluminium foil at 20 cm away on the left


9) Crumbled Aluminium foil at 20 cm away on the left
