Often times I shoot a bracket sequence to insure desired details are available; most often I simply choose the image I feel is best and then tweak to my liking. I was reviewing some of my early work with Photo Raw and came across an eight image bracketed sequence from which I had created an HDR. I had much trouble editing a single image from that sequence to match the HDR (which I didn't really like all that much). Starting completely over with HDR and then a single edit I was totally amazed at the noise level differences; no noise reduction nor sharpening applied.
My take-away from this >>> shoot brackets whenever possible; use exposure blending / stacking / HDR to reduce noise and increase sharpness.

That worked quite well Peter.

Thanks, Peter. I appreciate you sharing how you worked with the photos and including the examples. I remember a similar post in the past that was very helpful.

For this bracketed sequence, when no-noise, sharpness, and detail is your intended goal, are you changing exposure settings for each shot, or several shots at the same exposure ?

To my knowledge using a bracketed set the camera changes the the exposures by one set you the user >>> maybe by plus and minus 1/3, 1, 2 ev.
In the situation when the subject is static and there's a possibility of high noise one can take advantage of noise stacking by simply shooting a burst set; since noise is random stacking will remove the noise.

That makes good sense; I read "bracketing" and my mind then wanted to complicate the issue; sooner or later, it would have dawned on me that it would be as simple as holding the trigger down for a second.
As for varied exposure brackets, I hadn't thought about it; but, I guess merging the images into HDR would alleviate most or all of the noise as well.

Yes the random noise will be reduced when merging to an HDR, but one doesn't have to merge into an HDR, instead use the image set for just noise stacking. |
