tri-x1 Posted May 30, 2008 Share Posted May 30, 2008 I don't think you can set the ISO or aperture so that a 30 second daylight exposure won't be white (totally overexposed). Thirty seconds in daylight is a long time. You said you had changed shutter speeds but also said the exposure was 30 seconds. Link to comment Share on other sites More sharing options...
lwg Posted May 30, 2008 Share Posted May 30, 2008 Most likely you have too much light. You will need to use a neutral density filter to cut down the light levels. They are measured using a log scale, so a .3 will reduce the light by 1/2 (1 stop), and a .9 will reduce the light by three stops. Sounds like you also need a basic tutorial on exposure.

david_dorcich1 Posted May 30, 2008 Share Posted May 30, 2008 Lo-1 on the d300 is iso 100, assuming you are shooting something in direct sunlight you would need an 11 stop ND filter to shoot at even f22 for 30 seconds. Link to comment Share on other sites More sharing options...
Peter_in_PA Posted May 30, 2008 Share Posted May 30, 2008 Phil, WHY are you trying to get a 30sec daylight exposure? What are you shooting? Link to comment Share on other sites More sharing options...
alan_olander1664878205 Posted May 30, 2008 Share Posted May 30, 2008 A 30 second daylight exposure would overexpose at even the smallest lens aperture and the lowest ISO. Get the book "Understanding Exposure" by Bryan Peterson. Link to comment Share on other sites More sharing options...
