Hello,
I shoot for a local magazine and oftentimes get to do home interior shots. One problem that has always plagued home shoots is the blown out windows you get because of the outside light. It has become acceptable, however, as you can see in any national home magazine. But I did a shoot yesterday, and the house had some exceptionaly large windows. I used it as a chance to try my hand at HDR and process the images to get a more even exposure. I came up with several that I like.
Here's the question: Will taking the image to 16-bit cause any problems when it reaches the printing process? I want the image to look great when it reaches the paper. |

I'd be surprised if the process were unable to handle 16-bit images, but if that proves to be the case it's a simple enough matter to convert the HDRI composite image to 8-bit, and very little (if anything, practically speaking) will be lost.

| Well, now that I have brought it all up, I have to display my ignorance. What is the difference between 8, 16, and 32 bit anyway??? |

I recently used the HDR process for some interior shots I did. The results were great. These rooms don't have any windows. (home theatres). The lighting in these rooms is rather of a high contrast with the small pot lights in the ceiling and any wall sconces. As you can imagine the shadow areas are very dark.
I still add my own grid spot lights on the areas that require them (only using the tungsten modeling lights)
I shoot RAW with the camera set for the incandescent colour balance and make my bracketing exposures from there.
I ran the HDR straight from the RAW files (16 bit). Did a couple of adjustments after the HDR and got some terrific results.
Cheers

| Along the same lines as the original question. How well do HDR pictures print? I've played with a few, and granted I pretty much suck at them, but they seem to have some weird 3d-like effect with red and green lines around some of the edges and stuff. I dont look as 'clean' as usual prints. I guess I should print one out and see for myself, but I'm not expecting them to be good. How good can they be? |

I work at a printing company and we handle pretty much the entire gamut of printing. 16 bit is used mostly when manipulating images - 8 bit is what you're gonna end up printing with in most cases. You can save the 16 bit in case you want to make changes later on but the 8 bit should be fine assuming your resultion is high. Also: there are some design apps that will not allow usae of 16bit.
One more thought - images will prinjt as CMYK I assume, so you might want to make this conversion as instructed by the appropriate dept at the printing co.
