Recently, I discovered this club in deviant art for HDR photographers and digital artists. I was amused when I saw their gallery. The photos were stunning and it looks kinda surreal. It's kinda hard to explain so here's a few quote's from wiki "high dynamic range imaging (HDRI or just HDR) is a set of techniques that allow a greater dynamic range of luminances between light and dark areas of a scene than normal digital imaging techniques or photographic prints. This wider dynamic range allows HDR images to represent more accurately the wide range of intensity levels found in real scenes ranging from direct sunlight to faint starlight." Here are some photos that I tweaked to have this HDR look that I was talking about.
I also made an action for photoshop in case you want to see how your photos would look like with the HDR effect. Click here to download the file. After downloading, open your image in photoshop. Then, go to the actions window (Windows > Action or alt+f9). In the upper right hand corner of the palette is a small arrow (
or 
). Click Load Action. Locate the action in the dialog box and click OK. Now, you can see the HDR folder in the actions palette. Click the arrow to show the actions of the folder. There are three actions. First, choose the HDR Effect. Click the play button 
at the bottom of the pallette. Wait for a few seconds and see the results. Here is a sample of what it will look like before and after the action is applied.
Results may vary depending on your photo. It also works best in dark landscapes like the one that I used above. When I used portraits, the results are very vivid so I created the Desaturate action. If you think the colors are too saturated, use this action as many times as you want. If you want to have a retro look, you can use the Retro color action. Here's the result when I applied the action to the last photo above.
Isn't it cool? I wonder how your photos will look like if you use the actions. Contact me or a post a link of your work. For more photos, check out my multiply site here.More on HDR:
