HDR from one jpeg, and it worked.. i think. C&C

D-B-J · Apr 14, 2010

So, i went and stood in a tree for about 20 mins and grabbed a few macro's of the buds (its a peach tree i think), and when i opened it up, most of the highlights we blown, and some of the shadows were underexposed. So i took the jpeg into photoshop, and changed the exposure settings by adjusting the curves. Put them into photomatix, set them at 1 ev step a piece (figured that would be close enough), and i am rather happy with the result.

Please comment and critique.

After the HDR:

So essentially all you did was tonemapped a jpg.

Either way I like the after effect

However no need to go over something that has been mentioned so many times by myself and other so here's a quote not being a D about it but knowledge is a tool that should be used.

HDR WIKI

Source Wiki HDR
"
High-dynamic-range photographs are generally achieved by capturing multiple standard photographs, often using exposure bracketing, and then merging them into an HDR image. Digital photographs are often encoded in a camera's raw image format, because 8 bit JPEG encoding doesn't offer enough values to allow fine transitions (and also introduces undesirable effects due to the lossy compression).
Any camera that allows manual over- or under-exposure of a photo can be used to create HDR images."

Thanks. And yeah, the after affect seems to work much better than the original.

i was under the impression that hdr is any form of overlaying multiple EXPOSURES ontop of each other, whether they be attained by auto-bracketing, converting one raw into 5 jpegs, or one jpeg into five.

You cant simply take a single jpeg and by using Exposure tool in Photoshop over and underexpose the file to create a complete dynamic range image. You can improve the original jpeg file but it will not compare to separate shots with different exposures done by the camera and not by software.
