Dear All,
I am writing to enquiry whether the instruments that I selected are apporiate to record the LDR and HDR images.
Camera: ESO R8
Lens: Sigma 8mm F3.5
I have attached the specifications of these instruments.
Looking forward to your kind suggestions
Regards!
Joe
Hi Joe,
It’s difficult to say for sure from the specifications how well a camera will perform in multiple-capture (a.k.a. Auto Exposure Bracketing or AEB) mode. The main concern is that the photographer can switch off any auto tone-curve and auto white-balance features on the camera and shoot with a neutral color and response behavior. You are asking the camera to act like a colorimeter, basically.
While we shouldn’t recommend specific brands or products on this mailing list, there are resources available that list various camera capabilities. Here is a good example:
For a general introduction to the requirements of HDR capture, you may also find this page useful:
While you may not be shooting real estate, most of the same principles apply.
And finally, a plug for the upcoming Radiance workshop in Switzerland this August, which features a day devoted to HDR capture on Friday the 29th. See the following link to the official EPFL website.
Cheers,

Hi Greg,
Many thanks for your warm suggestion!
It’s very useful and helpful!

Hi Greg,
I follow the steps to complete the camera setting for capturing HDR image.
However, I still have a question about the setting of the shutter speed.
Could you please kindly recommend a normal setting of the shutter speed? 1/80? 1/100?
Warm regards,
Joe
Hi Joe,
The light level and lens aperature (which should remain fixed during the sequence) will determine your minimum shutter speed. If your camera produces a histogram, make sure there are no (or almost no) pixels above 3/4 the maximum value. Some cameras will even show you areas that are over-exposed in each channel, which is what you should try to avoid on your shortest exposure.
From there, you should attempt to capture at least 7 exposures separated by 1 EV (a power of 2) or at least 5 exposures separated by 1.5 to 2 EVs.
Best,
-Greg
Well received. Thank you very much
