Played around with HDR (PW 370Z)

HKYStormFront · 01-25-2010, 11:20 AM

those aren't bad looking shots of ur car vipor but they don't look "HDR". plus taking one picture and turning it into an HDR by upping and lowering the exposure in post doesn't yield the same results as shooting +2 and -2 EV in the field. you can't create detail in the shadows and highlights that wasn't there to begin with. not saying there's anything wrong with doing it that way, just not the same results

vipor · 01-25-2010, 11:23 AM

ah, shows what I know. I was told they were, so I thought they were. They still do look over exposed and such, but I see what you're saying about the difference.

Typically, with HDR you are taking about 3-5 shots of the same image but in different but equal exposures on a scale. Like for instance: -3, -1, 0, +1, +3. This will give you extreme lights and extreme darks. You take those 5 images and import them into PS as and HDR composition and PS will allow you to edit and compose the single image. Typically, I have a stand for these kinds of shoots cause I cant hold the camera still enough and get 5 identical shots at different exposures.

I hope that kinda helps explain some of the process. I will find one of my old HDR's and post it up.

These are my 2nd and 3rd HDR attempt. I'm also learning this little by little.

Not bad

I tried photomatix and really liked it but wasn't willing to pay $100 for it. I used qtpfsgui for my shots. It's free and produces very similar results. Takes a bit more effort but isn't too hard to work with. I just downloaded Gimp to see if I can use it as a substitute for Photoshop. I like PS but again, don't want to pay $100.

Actually I took these pics with a Panasonic FZ35. You can find them for just over $300

Oh and nice shots of the car but I agree that they probably came from a single original. I've seen pretty good HDR effects from using a single RAW file but it seems that taking multiple shots is preferred.

makes sense now

like a multi-shot setting with different exposures, then layer it up. sweet. hard to do hand-held and keep it stable?

I'd definitely recommend a tripod. Some cameras have a bracket feature where it will snap multiple shots at different exposures automatically. You could probably get away with handheld shots that way but I'd still just use a tripod.

I could definitely get some codes but they probably aren't supposed to be posted on here. Rapidshare = win.

Hell yeah! Can you PM it to me? Thanks

puckshaw · 01-25-2010, 07:59 PM

Bah I suck at this. I'm not having any luck producing the same results at high resolutions. Any HDR gurus have some insight on why I'm having so much trouble? I've tried tweaking everything in qtpfsgui and photomatix. It either turns out noisy as hell or completely undramatic.

HKYStormFront · 01-25-2010, 08:53 PM

and that's why i've gotten to the point where i just don't even mess with HDR, especially for cars

bsramzy · 01-25-2010, 08:58 PM

you've already heard it , but i love shot #3.

6spd · 01-25-2010, 11:27 PM

less photomatix, more photoshop! photomatix seems AWESOME at first but looses its flame quickly. making a picture with high dynamic range is very complicated and involves many different layers and much time. every aspect of the picture has to be tweaked separate from the rest, hence the many layers!

What file format are you starting with? If at all possible, use RAW files instead of JPG. I've played around with qtpfsgui from time to time. I think you can get some pretty cool stuff out of it.

You guys want to talk about awesome, check out these pictures of various Formula 1 races using Tilt-Shift Photography .......

I'm sure someone on this board with a better aptitude for complex ideas can explain how these images are created.

That, or I guess I can wiki it and find out
