the center value with or by the factor.
Example:
I want the center exposure to be 2 seconds. I want to take 3
pictures with EV(+-) equal to
½
. What will be the exposure values?
As the EV(+-) is set
½
, the factor is 1.41. The center exposure will be 2
seconds. The high exposure will be (2 *1.41) which will be rounded to 3
seconds. The lower exposure will be (2/1.41) which will be rounded to 1.5
seconds.
Example:
I want to take seven pictures in total but the lowest exposure
is faster than my camera can go in bulb mode. What will happen?
In such a case the speed of your camera will be the lower limit for the
exposure. It is possible that you get two pictures with the same exposures for
the lower values.
IMPORTANT:
Your camera must be in BULB mode to take HDR pictures.
Otherwise, all of the pictures will have the same exposure.
After you have all the three parameters set, you can press the start key. After
this, a time line will appear on the screen with the calculated exposure values
and stops. You will also see the current index of the picture to be taken along
with the total number of the pictures to be taken.
