Exercise 9 Scene Dynamic range

In this exercise, I am required to take 5 different scenes , Doing the same as before, in the last exercise. But one picture must have highlights, (high dynamic range ) And the other showing one that is flat. (low dynamic range.)


Any scene will do for the rest.

 Exercise 8
I cant help thinking , that the 400d s Dynamic range is not so good in the lower range to record detail, Where as the 7d tends to burn out high lights, Hens, the reason it has a highlight clipping mode .

Conclusion:

Most certainly, there is more to digital then meets the eye.  So In future I must remember, when setting up the 400d, to open up a stop. bracket , this will be to allow detail in shadow areas,  And stopping down, I found with the 7D

Not all camera are the same.


fist low light

1/80 f5,6 ISO 200 
 second high light
Even ditail in High lit area of intens light get washed out and become hazy.


!/80 F 14.ISo 200 

 The next three are and average of lows and mid rage and a hint of high dynamic range.


1/80 f 5.6 ISO 200 
Some noise , just slight is fund at 1005 magnification in the shadows of this pot and upper left side.  



1/80 f4.5 IS0 200 


1.80 F5.6 ISO 200 

Moving in close and taking an exposure, assures that the range of shadow area retains detail . Providing the highlights do not burn out. Using the TV mode keeping the shutter the same. You can see how much the F stops differs from the above.
