Thumbs up Why I like HDR Photos...

Wezbian and I held a mini photoshoot for a friend of ours on G35Driver last night in Old Sacramento.

I've got a lot more pics in the editing queue and will be posted in a new thread later. This is just a teaser to show off the pros of auto-bracketing for HDR merging.

Photomatix Pro

It does a great job and needs very little touchup in photoshop afterwards.

How is HDR shot? Is it seperate photos or does the HDR camera's do the work for you? (besides angle, lighting, and those other variables.)

if you look at the first post, there are three clickable thumbnails. these three photos are shot in succession. the camera shoots the normal exposure first, then dials the shutter speed down and shoots the low (-2) exposure next, finally, the camera lengthens the shutter speed and shoots the high (+2) exposure.

once you have all three, you can bring them in to photoshop to correct white balance or what have you. once done there, you import into Photomatix and generate a crude HDR shot. After that, you use the Tone Mapping function in Photomatix to make it look cool (artsy or realistic - your choice).

the benefits of HDR - which are visible in the final above - is that it takes usefull information from all three shots and makes them visible in one total image.

you can tell that the low exposure isn't really used in the above shot. mainly the 0 and +2. the 0 shot provides most of the detail, while the +2 shot gives the detail of the inner part of the rim and rotor to the final pic. subtle but effective.

HDR is the merging of 2 to 3 pictures taken of the same exact thing, but in different exposures (as he shows you in his first post)

So a Tripod is definitely a neccesity when taking HDR shots. I thought I'd seen some rolling shots in HDR, that must be a bitch keeping steady.

you can make a quasi HDR shot from one single RAW file from a camera. with a RAW editor, you can change the exposure of the image and generate three separate JPGs at the exposures listed above. from there, you repeat the above process.

i've tried both, and they both work. However, the three separate shots turn out better with the true image information captured at that particular exposure.

Well I know who I'm PMing if I ever look into upgrading from my point and shoot camera.

If I didn't mention before, cool shots.
