“Waterfotografie is een van die kategorieë van fotografie waar geduld en ‘n baie stewige driepoot van groot belang is,” het Robert Johnson, Gansbaai Fotografieklub (GBC) Maandag, 6 Februarie 2016 gesê. “Soos in die geval van alle wenfotokombinasies, moet die fotograaf bereid wees om hard vir sy foto te werk.”
Enige vorm van waterfotografie is aanvaarbaar, solank water die oorheersende onderwerp is: Lopende water; watervalle; dou- of waterdruppels; stormagtige water (die see); damme; ys en selfs stoom.
The exposure triangle have to be taken into consideration in photographing water: Shutter speed - freezes or blur the movement. The faster the shutter speed, the less light is let through; Aperture - depth of field. Open the aperture to let in more light; ISO - sensor sensitivity. Adjust ISO to make the sensor more sensitive to enable more light to come through. (ISO stands for International Organisation for Standardisation).
Points to remember: To freeze movement - fast shutter speed; to blur moving water - slow shutter speed.
“Tips” for photographing waterfalls: slow shutter speed (2 seconds+); first or last light of the day, or an overcast day; tripod; ND Filter is needed – slow down; wind may have a negative effect on the background; Use a polarising filter for glare at the bottom and glare on wet rocks; Be aware of people or debris nearby the waterfall, however, people can create scale.
Dit is maar enkele wenke tydens Robert se gereelde opleidingsessies wat die moeite werd is om by te woon.
