I've taken some time off from shooting and was testing today with my Nikon D100 and Sunpak 555. The histogram touched the right side of the graph but didn't bunch completely on the right side. The whites in the scene blinked as if overexposed. To avoid that though the rest of the image would have been under exposed. Is it normal for the histogram to touch the right side as long as the entire data isn't pushed into the right side? Let's say it's a white wedding dress...Is it normal for some of the white to blink as long as the majority of the dress isn't blinking/overexposed? Thånks!
