Aye, HDR files are still only 32-bits per color, but they use 16 and 32 bit floating point operators for the "dynamic range". Jpegs are considered low-range, they are 24-bit files with lots of noise... That's 8 bits per color channel (RGB). A 32-bit HDR image contains the same 8-bits per color (RGB) and another 8-bits floated through the pixels through all of the first three color bits.... Fun stuff! HDRSoft site : "Ideally, an HDR (High Dynamic Range) image has a dynamic range that reflects the ranges of real-world scenes and this can be quite high (ratios of 100,000:1 are common in the natural world). However, the label HDR is sometimes used for any image that has a dynamic range greater than the 255:1 ratio of 8-bit images. More commonly, the distinction is made depending on the number of bits per color channel that the digitized image can hold. 8-bit images (i.e. 24 bits per pixel for a color image) are considered Low Dynamic Range. 16-bit images (i.e. 48 bits per pixel) are still considered Low Dynamic Range, but they definitely have a higher dynamic range than 8-bit images -- RAWs produced by standard digital cameras (12-bit sensor) have a maximum dynamic range around 4,000:1, RAWs from high end cameras (14-bit sensor) around 16,000:1. 32-bit images (i.e. 96 bits per pixel) are considered High Dynamic Range. Unlike 8- and 16-bit images which can take a finite number of values, 32-bit images are coded using floating point numbers, which means the values they can take is unlimited." Open EXR (hdr file type) : "Support for 16-bit floating-point, 32-bit floating-point, and 32-bit integer pixels. The 16-bit floating-point format, called "half", is compatible with the half data type in NVIDIA's Cg graphics language and is supported natively on their new GeForce FX and Quadro FX 3D graphics solutions." HDRShop specs : "The HDRShop 2.0 plug-in for RAW images imports the full 12bit dynamic range of Canon RAW image, while providing control..." Another great site, but really, REALLY technical reading for me... http://www.anyhere.com/gward/hdrenc/hdr_encodings.htmlI don't think I'm good enough to beta test such an excellent terrain map. I could certainly beta test a tutorial using them though - let you know if it's easy enough to follow (ggggg)

After making some organic terrains map.. here is my try at mechanical stuff... tu use as a background or whatever!
