HDR Pics
 

How do you HDR a photo? I have photoshop but not the full install. I can do layers and all that but I am lost in the whole thing.

google: photomatix

this is in the wrong section

Take at least 3 pics at different exposure rates (usually -2,0,+2), and put them together in a program like photomatix. You could also cheat and take one photo and change the exposure in PS to -2 and +2 and then use your HDR program.

first you need to take several shots at different "stops" (vary the shutter speed). 3-stop difference should be enough. The images have to align perfectly so a tripod & remote is a must to prevent camera shake. HDR basically creates a balance from the overexposed & underexposed images.

In Photoshop: File>Automate> Merge to HDR> Browse(select files in order)>OK

After it processes the images you can adjust the historgram

:iagree:

I thought it was about Headers.

another cool program is Oloneo - it's in beta right now so it's free to try but the results i got from it are great!

If I post under GENERAL DISCUSSIONS..how is this in the wrong section?:confused:

Thanks for the information tho guys, sounds abit confusing to me. I'll give it a try.

370Z General Discussions, we have a photography section now specifically for questions like this

Hdr?

I did not know about that..... and the enhancements ARE for the 370Z :p

There are ways to fake HDR in Photoshop with a single image, but it's actually more complicated than doing it properly.

In case I sounded confusing, here is a link I found:

High Dynamic Range (HDR) Photography in Photoshop

Jeebus that's a lot of work... checking out a tutorial for CS3 on youtube right now...

I can shoot the auto bracketing with my camera so that's a good start. I will keep researching this...

this is why i :facepalm: whenever someone posts an HDR image or asks about them

^^^ lol

From a single image... decent tutorial.

if you want 9 stops of dynamic range, the right way is to shoot film and scan it to edit in photoshop, not HDR (digital only sees 5 stops of dynamic range, human eyes see ~12 stops)

What's film? ;)

<--- never shot with film... ever. yay for digital!

I think it's like a Polaroid. Never heard of it.:roflpuke2:

Oh haha... nice. I started with film but yes... thank god for digital!

I had film on my camera once... but I wiped it off.

Not to be pedantic, but to be pedantic :)

Varying shutter speed isn't relevant unless in full manual mode, and even then is incomplete. What you need to vary is exposure, either by using exposure compensation or bracketing, or by using full manual, in which case you can vary shutter or aperture, though aperture variation may create depthnof field artifacts.

Also, digital has more dynamic range than film, but less latitude - like an excellent slide film, especially when shooting RAW, which has a coulee of extra stops of range. It is possible to create an HDR with a single raw shot.

Finally, a true HDR can't be represented in a JPEG file which has a fixed range based on format, or displayed on a normal (non-radiology) computer monitor, which also is restricted in dynamic range. The best you can do is convert the HDR back down to normal 8-bit dynamic range using a custom tone curve. That said, properly done such an image can feel more like what you saw in real life.

^^ good explanation, but I'm pretty sure that's gonna confuse the OP even more.

Haha so true..

AWESOME. Where did you get that graphic? I want it for my office!

This graph is brilliant. I want to show it to some folks who think they are pros the second they bought their first dslr....might give them some perspective and show them that its not the camera that makes fantastic photos...

My iPhone 4 has built-in HDR now! :D

someone posted it on a photography forum that i'm on, i seriously fell out of my chair laughing because it is sooooo true :bowrofl:

i'm currently in the "damnit, i suck" section of that graph, mixed with a little bit of gear-faggotry as we were talking about the past few days lol

Keep at it. I've been shooting for 40 years, seriously for over 35 (got my first camera at 10). Still learning and getting better every day.

Shooting in RAW makes it very easy to get different exposure levels from a single image.

True, but typically only a total variation of two stops. For wide latitude scenes, exposure bracketing or exposure compensation and ideally a tripod are the way to go.

I shoot my Christmas decorations at night that way, typically as a stitched panorama as well.

I have an iPhone and they just incorporated HDR into their camera. I have noticed a huge difference in the quality. I took of a picture of my kitchen and the light around the window is significantly washed out with a non-HDR camera and looks great when using HDR.
I am not sure how it works, I think it is in the software. Hope this helps.

The chart is great.
