I also noticed that it seems to work on and off lately. I sent an email to the contact email on the site (contact@createhdr.com). I’ll let you know their response when I get it.

Technically, that’s not really HDR. HDR is a method of making a picture where you can see what’s in the shadows without blowing out the highlights and vice versa.

You need to shoot multiple exposures of the same scene, with widely varying exposure ratios (I’ve been trying using 5 images from 2 stops underexposed to two stops overexposed, though I could go higher – 4 stops each way is not unheard of), then process those into a single image. What you get at this point is HDR but not displayable on normal hardware. (Typical PC hardware displays 8 bits per color; HDR can have 32 bits per color) You then go through a process called “Tone Mapping” to reduce the image back down to something your computer can display. It’s the tone mapping that creates that hyper-realistic coloring. But, what you’re not doing here is bringing up the dynamic range of the image.
