haverford college duck pond

i'm experimenting with hdr again. this one was a struggle. the exposures were too long to keep the fast-moving clouds in the sky from going wonky over the series of exposures. then there's the artifacting. no matter what i shoot, what settings i use to generate the hdr, whether or not i use a tripod, photomatix creates artifacts somewhere in almost every one of my images. i shot a test series in my apartment on a tripod facing a window (for the range of indoor vs outdoor light) and got strange line artifacts all along the window frame. yet people are doing beautiful hdr work with this application, so either they are spending lots of time repairing that crap or it's user error on my part.


come to think of it, it seems to consistently happen in areas of extreme contrast difference. i'll have to test for that.


anyway, this is a great campus that boasts not only this lovely pond, but a sweet walking trail populated with a scientific tree collection. :)

    I like the color of the sky.
    Sorry, cant help you with photomatrix. Havent started using it yet. It's time I should though.

    I've since discovered that yes, Photomatix is not a one-stop solution in the HDR process. The ones who are good at it are taking the file generated by Photomatix, bringing it into photoshop along with the original bracketed shots, and then they use masks to bring back in the detail, correct artifacts, fix skies, etc.

    With the sky, it would've been helpful if I'd had a neutral density filter because I could've made the shutter speed slow enough on each exposure that the sky would've appeared smooth and silky instead of a blotchy mess that I had to repair.

    The image below is a more recent HDR that I've processed. Because I shot it handheld, many elements didn't line up and there a was major amount of artifacting. I wasn't able to resolve all of it, but I did mask in a lot of detail from the original shots, as well as using the clone tool to make repairs. Certainly this would have been a lot easier to process if I had shot it on a tripod, and it is a hard lesson that yes, HDR's should always be shot on a tripod if possible, even if the exposure times aren't that long.

    Here's the image I'm speaking of:

    I hope this isn't too detailed or nerdy for you. I'm quite interested in photographic technique and therefore enjoy talking about it. maybe too much? hehe :)
