marco_ritelli Posted March 26, 2005 Share Posted March 26, 2005 What happens if I have an ISO400 film loaded on the camera, and for necessity I change the ISO setting to ISO 800 or higher to take a shot in low light without flash? Is there the risk that nothing will come out when I'll go to develop the film? thanks Link to comment Share on other sites More sharing options...
michaelging Posted March 26, 2005 Share Posted March 26, 2005 Marco, The second photo will be one stop under-exposed. With most negative film ,especially B&W you will get a printable photo off both negs. If the second photo is more inportant than the first you could push the roll 1 stop in developing it and the second photo would then be a proper neg, and the 1st photo would be one stop over-exposed. In eather case unless you are shooting color transparency film,you should get a printable photo off of both. Link to comment Share on other sites More sharing options...
michaelging Posted March 26, 2005 Share Posted March 26, 2005 To make it more clear, you can rate any film at a different ASA ,but to get a proper print you need to push or pull the film to match the ASA you are shooting at. This means leaving the film in the developer for a longer or shorter time to match the developement to the ASA setting you used. I hope this helps Link to comment Share on other sites More sharing options...
randrew1 Posted March 26, 2005 Share Posted March 26, 2005 I under-expose all the time at basketball games. Most color neg films will allow one stop under-exposure with good results (not ideal, but still good). In some cases you can get to 2 stops under. I'll shoot normal with a flash and 1 under without. (I can shoot rapid sequences without flash. My flash takes too long to recharge.) For a 1 stop shift, I don't bother with pushing. Push processing doesn't really increase the true speed very much anyway. (I judge "true speed" by the shadow detail.) Push processing mostly increases the contrast.

marco_ritelli Posted March 26, 2005 Author Share Posted March 26, 2005 I tried the inverse, with an ISO800 I shooted at ISO 600, the result? darker pics, but for me the result was better, because when you're shooting fast moving subjects with with centered-weighted metering camera you can't esteem the amount of reflection on them caused by the sun. Two examples: http://www.photo.net/photo/3227601 ISO400@400 http://www.photo.net/photo/3227609 ISO800@600 http://www.photo.net/photo/3228049 ISO800@600 As you can see the subject in the first pic is a little overexposed. well I think the contrast is better in the last two, it's just personal taste... Anyway do you think it's a good thing to set always a lower speed of the film in use in any situation? Link to comment Share on other sites More sharing options...
david_m Posted March 27, 2005 Share Posted March 27, 2005 You moved the dial in the wrong direction! To get more exposure, set to a SLOWER film speed rating. To get less exposure, set to a FASTER film speed rating. There is no problem with doing this whatsoever except you may forget to turn the dial back after the shot and ruin the rest of your exposures. Some intellegent cameras automatically reset after you take the shot. Link to comment Share on other sites More sharing options...
marco_ritelli Posted March 27, 2005 Author Share Posted March 27, 2005 So it's better adjusting the exposure compensation dial, at least you remember you have changed it because you have a red light in the viewfinder. Link to comment Share on other sites More sharing options...
