  • Night time HDR

    Hi all,

    Just thought I'll post some night time HDR I shot a few days ago. All were combined with Picturenaut. Then they were tone-mapped with Photomatic and post-processed in Photoshop CS. Tell me what you think.

      Re: Night time HDR

      Not many pointers. This was really my first try with HDRs at night as in general HDR is not my forte.

      I mostly used 3 exposures with -1,0,+1 (13sec, 8sec, 5sec). On one or two I have blended 5 exposures from 20sec, 15sec, 13sec, 8sec, 5sec. Depending on the image it may be smoother compared to just 3 exposures and tends to bring sky out better.

      The hardest part is that despite multiple exposures the histogram will be relatively left handed meaning still a lot of noise in shadows. It proved fairly hard to eliminate even with edge masking and may require quite a complex mask if you want to retain as much details as possible.

      Also I had to lower gamma on most photos to bring them back into darker tones.

      The other side effect of HDR merge is a really strange colour casts which can be difficult to neutralize completely.

      At the end it is like depend on the subject itself. If the subject occupies main part of the frame and is relatively light against the dark background (sky or sea) then HDR will likely give you a slight edge by opening more tonicity in the subject. However if your subject is relatively small compared to the rest of the frame you are better off just bracketing your exposure and finding out which one seems to have a better overall feel then perhaps manually overlaying them over each other and using masking to blend by hand.

      I am planning to go back and play with some other photos from the shoot later to see if I can get better results than with HDR.

        Difference between HDR and faux HDR
        by Boneappetit
        This question had been running in my mind for a while, so I would like to know if there's a real difference between shooting different exposures of an object or creating different exposures using Camera Raw?

        Long story short: Some (purists) don't accept works done, out of a single photo...

        should i use hdr or photoshop masking???
        by modelsfret
        when combing multiple exposures for interior and exterior architecture shots, my method has been to import each exposure onto multiple photoshop layers then mask in areas from each exposure. it seems to give results, but is hdr a better/ industry standard way to approach this?

        Photomatrix HDR Walk-Through

        Lowell Franga sent me a set of four exposures from the interior of a German church. He asked me to use Photomatrix Pro to demonstrate how I'd go about extending dynamic range.

        Well, this coaching session goes a bit beyond Photomatrix. To get as much detail as possible in the stained glass,...

        HDR exercise (Candle)
        by Doug Nelson
        It seems to me a lot could be learned about HDR from a shared simple exercise. How about your camera on a tripod, and a candle on a table? Put a book or something else interesting with fine detail next to the candle. Light the candle, turn off all room lights (needless to day, do this at night), then...
