Hello, I have a D5300 cam and having a problem whenever I take photos in our Services, because the stage has a LED Screen as a Background and whenever I take a picture, the outcome of the LED Screen is changing with every Zoom-In/Out, thus affecting the quality of the picture. I’ve tried to adjust the ISO, Aperture and Shutter Speed but there is still a problem Any suggestions you can give? My Lenses are 18-55 VR II, and 55-300 VR.
