Well, it doesn't seem to show off the capabilities of the HDR process. Plus, the sky probably needed a circular polarizing filter, as it's washed out on the left. I understand that it was much darker in the room and the plants look good, but I would try something else. There is a man on these forums who is fantastic with HDR. Can't remember his name for some reason, but he might have some tips for you. My attempts at HDR were very amateurish at best, so I'm not really the best one to give advice on this!

Once you get the art of HDR down, try a panoramic HDR! Yikes.

Ugh. Administrator: Sorry about the size. I can change it if you want.

<edit> Fixed...

<edit> Fixed... Almost fixed! ;)
IMAGE POSTING RULES (http://photography-on-the.net/forum/showthread.php?t=74718) only allow pics 800 pixels or smaller. You can always just post a link to them, though.

Oops! Sorry! :o

Sorry to say I think you'll need to work on this technique a bit more to get solid results. The way the sky lightens as it approaches other parts of the picture like the window frame is a clear sign of tone mapping / contrast enhancement software not working so well. You want the sky to be either a similar brightness throughout, or a fairly even gradation, but you'll want to tweak your HDR settings to avoid the completely white rendering on the left. Otherwise, the picture just looks a bit smoothed and detailless throughout... not sure why that would have happened. There are so many ways to process HDR images, and so many software packages, that I'm afraid I can't offer any concrete advice on how you might improve these through settings in your software. If you post your originals (perhaps just three covering the range), I could probably suggest some settings and algorithms that I think work well in the free qtpfsgui software, which you could install if you have a Mac, Windows or Linux machine.

Cheers,

Tony

srry about the size, i forgot....

thanx for the C&C guys

In an HDR you should have the best of all worlds; looking at your image, if you had not mentioned HDR I would not have recognized your attempt, except for slight halo effects (which is common). I am far from an expert but here is one of my HDR attempts. Did you use different exposures? Or did you just try to use a single exposure? A true HDR image requires at least two different exposures. For the image below I used 3. It was my intention to make this look more like a painting than a photo.

Orig 3 different exposures I used.

i used 2 exposures for mine...ill give it another try soon

[rustyjaw]

You know, it would be really helpful to see the original exposures you used. It's hard to say how much the HDR helped in bringing out detail in shadows, or highlights just by looking at the end result. But seeing the information that went into it would allow a much more informed opinion, and possibly even some direct advice on how to get to get better at making HDRs.

Any chance of seeing those 2 exposures?

[togish1]

i dont think i saved them to the computer since it was just 2 pics i was going to mess around with....sorry....

[rustyjaw]

It's OK, I'd say next time save those shots, if only so you can test out different settings when you tonemap/merge then into an HDR.

so to achieve true hdr i should bracket? by overexposing and underexposing is that the samething as going up or down one or more stops?
i know stupid ?

[ALaS]

Do you take 3 pictures with different exposures or do you change one image with different exposures then HDR it up?

I will often use 5-9 different exposures. Manual mode.

that one is beautiful! Was it made in photoshop?

I used Photomatix initially. I then used Photoshop to adjust curves, and contrast. I believe I also used the high pass filter, it's been awhile.
