[Strike]Amazing[/Strike] Stunning HDR video (done with two canon 5d mk2 and software HDR processor)
The ability to produce HDR video is certainly an impressive achievement in and of itself, but I am personally otherwise less than impressed.

HDR is but one technique to overcome the inability, on occasion, of a camera to expose all areas of a scene correctly, i.e. a scene in which the range of contrast exceeds the latitude of the camera. An alternative technique, for example, would be to use Graduated Neutral Density filter(s).

Note the italics above. Generally speaking, the exposure latitude of a camera is most likely to be exceeded when shooting in the direction of or near to the sun. Contrast shooting away from the sun will be significantly less and may well fall within the camera's ability to expose correctly. This immediately begs the question: is there a need for HDR video given that some directions being shot do not require HDR processing? Additionally, as technology evolves, the exposure range capable of being captured by cameras increases. Methinks HDR's days are numbered. :) In any event, the HDR video linked to in the previous post has, it has to be said, the same issues as many HDR photographs:

1. Halos. For example haloing around the person in the video when he moves his arms. This is a major issue with regard to HDR images and, it seems, video;

2. An unrealistic, almost 'cartoon' look, though this maybe considered acceptable if it was knowingly sought after at the outset.

I love this shot, except I'd love to see the original. Was it shot with camera- phone?
Yeah, taken from camera phone. A 90 mile ride isn't the best time to bring a camera along. That extra lb. would be very noticable

I agree with everything you said, sounds like you know what you talking about. However regardless of imperfections in end result, This was my first time with HDR video. Is the result is highly unrealistic and almost cartoonish - yes, still very interesting and something you'd never achieve with GND filter
. The authors may not been looking for realistic effect in hdr, my guess much more realistic effect could be achieved by adjusting the hdr process parameters.

You made the video/that was you in the video? :eek:

True, in this instance using GND(s) wouldn't make sense. However, by the same token I'm not sure that the 'HDR option' did either...at least when considering the section of video with the person. There, when the under- and over-exposed video feeds are shown side by side, the under-exposed video is only marginally under-exposed. The sky is not over-exposed. Consequently, it is likely that the camera could have exposed slightly more 'to the right' and reduced or eliminated altogether under-exposure of the person without blowing out the sky. Even if it did, blown highlights could've been at least partially recovered in post processing if the camera shot in RAW format.

I do, however, appreciate that the point of the video was simply an exercise to show that HDR video is now possible. :)

The authors may not been looking for realistic effect in hdr, my guess much more realistic effect could be achieved by adjusting the hdr process parameters.
I agree, though given the enormous number of badly processed HDR images there are 'out there' I suspect ignorance plays a larger role than artistic intent in many instances. :(

:eek: Opsi-daisy - Sorry, I meant to say - it's the fist time i SEEN hdr video, which wasn't computer generated&rendered 3d enviroment :)

[I wish I HAD two Canon 5D mkII cameras for that matter :D ]

Some after math from tornado in The Plains, Ohio

Took a small walk through some the mess left from one of at least 8 tornadoes that move through Ohio on Thursday. This is The Plains, Ohio and the photos do not not show the scope of damage or the worse.

There should be a garage here

Damnit Mike! Prior to opening this thread I seen the current post as yours and thought I was about to be treated to a 200mm f/2 shot. :p

I took a panorama of the NYC night sky line last night. The original is just under 26,000 pixels wide, so I'm going to have to figure out how to post it haha.
