HDR Newbie Questions
I've just discovered HDR !!
Looked but cannot find a definitive answer, what would be a recommended range for bracketing, either auto, or manual, to achieve the best results. Both my digital cameras will only auto bracket maximum 1 stop, is a greater difference recommended. If so, what ? Also, 3 or 5 or more photo's, is there really a difference ? You valuable experience is welcomed. I've been playing with PhotoMatix HDR software, I have Photoshop 7 on my iMac, not CS2/3, not really understanding layers, is it possible to at least simulate HDR using layers ? |

a scene illuminates with bright sun light you intend to photograph may has
high dynamic range or simply means the brightness between highlight and shadow with details are too wide apart for the camera sensors to record faithfully. you will lost either the hightlight or shadow details depending on the exposure. HDR help to solve this problem by you taking two or three shots with different exposures of the same scene, i.e plus, normal, over and the HDR will take the best parts of the different exposures to stitch them into one good pix hence virtually recorded the full dynamic range of the scene.

If your camera has a spot meter mode, meter the brightest surfaces in the shot, then meter the deep shadow or darkest areas. Take two exposures, manual exposures, using these two values. |

Mine also only goes to +1EV and -1EV. I still do not understand fully, but what happen if you just take one shot and try to get underexposed and over exposed of the same image using software? Something like using Gamma correction in PSP. Will that also work? .. |

Aperture priority? I havn't done any of it yet but I know that if one use AP then one must change that the aperture in order to gain a different exposure? Is that what you mean? In AP mode, the camera will make the 'same' exposure by changing shutter speed, anyway. The camera must be set to 'fully manual' and the ONLY thing that changes is shutter speed. This way, the DOF does not change, as you've stated. -- xenarshooter |

I can't help with your question, but I have an even more basic one -- What is HDR? HDR stands for High Dynamic Range. You should try to google and type in HDR Photography. You will be surprised on the kind of images that produced using the technique. I came across the HDR a few years back. It was a website showing photos at the University of cambridge http://www.cambridgeincolour.com/cambridge-gallery.htm In short, the photos include all of the ranges of shades in a pictures so that everything is bright and sharp. If you take a shot inside a restaurant, you will notice the closest objects are bright but the back is dark. By taking a couple shots with under and over exposures, you are combining portion of the photo area to keep all in bright and sharp images. I guess the various websites can explain it better than me. Popular softwares to use include Photomatix, or Adobe Photoshop CS2. But I heard there are lots of others and even some freewares. Hope that this helps |
