HDR Game shelf

Chapel inspired me to make another HDR picture. My first HDR picture was essentially bringing multiple exposures into one picture. When you take a picture of the sky, it requires a different exposure than one for something which does not contain the brighter sky.

However, there are other uses that I see for HDR. Besides playing with saturation, you can also play with the color mapping that is almost hidden within a picture. There are contour maps that can be brought out at the same time that you mess with colors.

Photoshop offers four 32->8 conversion routines: Exposure and Gamma, Highlight Compression, Equalize Histogram, and Local Adaptation. The first three are essentially flat mappings with very little options. They did not mix very well with the lighting in this picture. Which was flat and even as well. So I went with the last option. In the toning curve and histogram section, you can define a mapping function. And here is where you can really play with it. I chose a result that was other worldly. And those funky colors create the same look and feel of the funky colors in other HDR photos. Well, the other extreme HDR photos that I have seen.

When taking this picture, I relied on my Expodisk. It is amazing how much different the lighting color is between different sources.

Expodisc lighting (fan on)

This is what the light looks like with the CFLs on inside of the ceiling fan. Keep in mind, this is at the same time as when the fan blades are spinning. With some of the light reflecting back down off of the dark brown fan blades, it gives the light a decidedly brown tint.

Expodisc lighting (fan off)

With the fan blades off, the light is much more even. And much closer to white (or grey in this 18% capture).

Expodisc lighting (flash)

And even with the fan’s light on, if I were to use a flash, the flash’s bright bluish-white light overpowers the other light.

I think that could then selectively pull in the HDR’s colors into the starting picture to create an emphasis. I would like to try this with Antiquity’s pollution markers in my next HDR picture. It would make them look more radioactive.
