My first attempt at HDR photo

[Yarbone]

this is my very first attempt at making an HDR image.

Since i don't have any experience at making them, i just thought i could maybe get some feedback here.
I hope someone does have experience at making these

Hi Yar..

Just trying to see what is HDR about this.... just looking at this one, the DR seems the same as normal or am I missing something?

I can see some processing on the background, and think this is one layer with the cube over the top (slight feathering on edges of cube). Do you have the original bracketed images to show?

IMHO, HDR works best with outside images where exposure proves more of a problem.

I.e. - a shot of black tarmac with bright sky. The problem a normal shot has is that the tarmac is at opposite ends to the dynamic range from the sky, so the original image with correct exposure caters for this. Unfortunately, the sky would not have a great contrast, neither would the tarmac.

The process of HDR seperates these areas and blends them so the exposure for each element offers greater contrast.

Photographers have to use things like polarising filters to overcome the problem without multi-bracketing.

For an indoor shot like this, I wouldn't think this would vary to much from the original.

I like the idea though!

hmm... maybe i could have tried something like a bigger difference in the exposure times between the 3 shots.

But yes, i've noticed that pictures of outside are really colorfull and pretty :3 So I might try making something else then

btw, if you see the differenence between this picture and the original 3, then I think you would prefer the HDR one
I will post them later

I've never tried HDR, but I would think it works best where you have a subject with a large range of tonal areas to show off the effect. This one does show it a bit, but the range is a bit on the bright side. What might work best is maybe try something with deep dark woods to bright sunshine. Or maybe night with lit up buildings. Basically where you have very bright as well as very dark areas.

Not sure how many shots you took, but I suspect if 3 shots you would vary it by 3 stops on either side of normal exposure and if 4 shots, bracket the shots by 2 stops per pic.

So like 3 pics.. 1 shot at -3 stops, 2nd at a normal exposure, then 3rd one at +3 stops

and 4 pics. 1st shot -4 stops, then 2nd shot -2 stops, 3 shot +2 stops and finally + 4 stops.

Hope that makes sense!

There is a ton of web resources on HDR it seems. That is just one thing I have not really tried yet!

Good luck!

[Yarbone]

hmm... i haven't figured out how to make a picture with 4 different stops, but yeah i understand what you mean. I think i did -2, 0, +2 on that picture.

But good news, i've made some new ones!

This one, and this one

On the first picture there's this weird red line around the top of the bridge... i don't know where that came from D:

I've taken a couple of HDR photos myself. U can do it the traditional way like its stated above or use the RAW file from one image in Adobe Lightroom. This way you can get different exposures for the the same image, getting no blur. If you're going traditional, I suggest you use Photomatix for the tone mapping.

I used a program called "qtpfsgui" O.o

Nice! Though I think probably the only real darks were under the bridge? Much much better than your other, but doesn't show off the effect as well as it might. In doing a bit more reading, depending on the shot it is not always simply over and under a particular exposure. Check out this page and look for the pic of the doorway arch and the castle.

Plus that is a pretty nice site in general for photo info.

Keep up the good work!

you should definitely git it a try. There's a full program and a plug-in for Photoshop as well. You can do some wicked stuff with it (even close-ups like the first image)

I'll try to make a more profesionall looking one later : D

Where can one find the PS plug-in? This HDR stuff is really good.

If you check their site you'll see that you can download plug-ins for different programs, including photoshop. There's a demo there but I'm pretty sure you can find the full version somewhere else
