Color slide film has much less latitude than negative film. If the exposure isn't "nailed" within about 1/2 stop it can easily result in photos that are either over-exposed (high lights blown out - just clear acetate film), or way too dark. I've shot a lot of color slides over a period starting in 1965, the most consistently acceptable results I obtained were after Nikon introduced their "Matrix" metering.
