HDR imagry

[MacStian]

So I´ve tried searchin the forum for something done on HDRI... I think I remember reading somewhere that Purplerose had been doing some HDR... But find nothing.

So who here has delt with this fenomenon? :rolleyes: I´ve recently been asked to be standby for maybe producing some HDR (High Dynamic Range) images. But I have questions. And would like to find others who have delt with or are in to this.

HDR is fun... The one image I've done in HDR is in my old photo thread in the old archived forum. Here's a link to it on Flickr though: http://www.flickr.com/photos/jerricaraglin/2151721533/

It's really useful for getting color in areas that are nearly impossible to get light to. The image I linked to above was mostly a dull brown at the bottom and on the trees the sky was also an ugly grey color. Processing it as an HDR image (using multiple exposures) I was able to get the lighter browns, greens, yellows and the blue in the sky.

HDR is also known for producing some over-the-top images as well.

Some general searching will bring up moderate to extreme HDRs. It's all a matter of personal taste and the final product you're aiming for.


Hope this helps somewhat. :)

In my scrapbook you can find some HDR's also ;)

I thought the HDR's where on the 2nd page.

Grtz,

Do you use the Import > Merge to HDR feature i PHS?

Thank you a great lot for your responses and for the look at your HDRs!
Frutsel: It seems your images is edited after merging...? Is this correct. Pasted here your image from your scrapbook. (Hope ths is okay!)

A HDRI may be used in a 3D application for getting all they can from the luminance in the image. The image is therefore 32bits/channel. Is it really possible to alter the image with postprocessing in 32bit?

With the progress of technology, there are some great possibilities to improve images. But when it comes to HDR, I find most of the pictures are flat, loud and most of the time, they're plain ugly. Most of them are totally oversaturated.

Form is interpreted best when there is light and shadow. That's the principle of form. When you remove the shadows, everything is flattened on a plain layer and the image looses depth.

My 2 c. I like traditional photography more.

Here's a good link: http://www.photoshopcafe.com/tutorials/HDR_ps/hdr-ps.htm

The tutorial says to start with 3 images, but you can easily use more.

Thanks for opinions and tutorial. Heres a shot I´ve done that is processed with Photoshops HDR conv. and Photomatix. The outcome is a result of the two different ways the conversions made me think of the image. And as mentioned earlier, yes, photomatix easily gave a lot of saturation that I´ve chosen to work on.

perfer the first

the orange on the brickwork in the second isn't very appealing imo

[purplerose]

I think I would prefer something that was between these two. They both have some good qualities depending on what they will be used for.

I would suggest to experiment more with the Photoshop HDR conversion. It allows you to play around more without having to resort to the sometimes over-the-top Photomatix results.

I have started yesterday to fake HDR imaging, using photoshop features. I'm still not satisfied, and I'm waiting for an occasion to shoot some building & sky stuff, just to get some better understanding.
As for the 2 pics, I usually like desaturated pictures more than colourful ones. Even though, I find the second one quite interesting.
