My D40 has Exposure compensation settings, but I've yet to use them!. Now that I am getting into night photography, I want to know what effect this setting will have on my shots!. Will there be excessive and noticable noise!? Will the shots look artificial!?Www@QuestionHome@Com
Best Answer - Chosen by Asker: Exposure Compensation (aka EV) is used when: A) The camera meter is fooled in certain situations!. One example would be a back lit subject!. The meter will set exposure for the overall scene and your subject will be a silhouette!. In this situation you'd use +1 EV and if that wasn't sufficient then +2 EV!. You are, in effect, overexposing the subject compared to the background!. The background will be blown out but you'll have good detail in your subject!. Another situation would be a front lit subject against a darker background!. Again, the meter will be fooled and your subject will be washed out (too light - little or no detail)!. Here you'd try -1 EV and then -2 EV!. Here, you're underexposing your subject compared to the background!. B) When you're unsure of the exposure you can "bracket" your exposures!. Sort of like the other poster said!. For successful night photography without flash you'll need a tripod and the FotoSharp (http://www!.fotosharp!.com) Day & Night Exposure Guide!. Contrary to popular opinion, there is no need to shoot wide open or at a high ISO setting unless your scene contains action!. Here are a few examples from the Guide: Floodlit buildings, fountains ISO 100 f4 @ 1 sec f5!.6 @ 2 sec f8 @ 4 sec f11 @ 8 sec Scene 45 minutes after sunset ISO 100 f4 @ 1/8 sec f5!.5 @ 1/4 sec f8 @ 1/2 sec f11 @ 1 sec City skyline in distance ISO 100 f4 @ 8 sec f5!.6 @ 15 sec f8 @ 30 sec f11 @ 1 minuteWww@QuestionHome@Com No No!. Exposer compensation just changes the automatic exposure by the amount you changed it!. Many professional photographers will take each shot 3 times, one at the camera's setting, one +1 stop over exposed and one with -1 stop under exposure!. For example if the camera choose 1/60 of a second the +1 would the 1/30 of a second and the -1 would be 1/125!. That is for aperture priority mode in shutter priority mode you would change 1 f stop in each direction for +1 and -1!. Sorry for confusing you bit if you experiment you will quickly figure it out!.Www@QuestionHome@Com I don't own that camera, but I am a big enthusiast of photography, and when I talk to people about special situations, they all say to turn off all the automatic settings!. Camera's are fooled quite easily and I would hate to see you depending on some computer chip making decisions about your shots!. What the person below me is talking about is called bracketing, and is a professional technique to get a set of shots that have slightly different aperature settings!. It's really good advice and many cameras will do it automatically if you set it that wayWww@QuestionHome@Com |
