high light clipping Exercise 6

 After going through the exercise on linear capture . And now reading this about highlight clipping, I can now see why the debate continues "digital will never out perform film. as the Latitude of film is so much grater. Digital is more like transparency with more limitations. So Technology has yet to over come these hurdles. Some how, I feel we are a long way off getting it right. Even after this course was written. I found the newer cameras are still not what I had hoped, after using medium format. Im a Fool for selling mine at the time.

The 7d I am now using. So much highlights are lost . Reading through. I have come to terms that when photographing with digital. The rules are some what opposite to film . Especially Black and white.

In black and white . The old rule of thumb , was to expose for the shadows letting the highlights look after them selves. However , here we need to expose for the highlights.

Here I have taken a picture, a side look of a work top. Exposing  correct exposure.  Then 1 full stop open, then stopped down 1 again 1 and then again 1 stop down :



starting at F 5 1/8 sec 400ISO
 1 stop up F4
 1 stops down 5.6
 2stops f8
 3 stops down F10

Depending on how much highlights are in the scene . I note that the top picture, highlights or white areas have lost all detail. Average exposure still lacks detail on the second photo. By stopping down 1 stop . This holds details and colour . 2 stops down, still holds detail in the highs and the lows shadow areas . 3 stops down, and shadow areas starts to lose detail.
