I was testing the new Nikkor 200-500 mm f/5.6 VR lens for close quarters shooting!
My Friend Sunil Sharma was doing something and I chose to click him for testing the lens and also giving my friends a glimpse of White Balance working.
The pictures have been clicked seconds apart and thus as such there was no notable change in light conditions and other external factors.
All these pictures have been clicked on Nikon D7100 with Nikkor 200-500 mm f/5.6 VR lens at 300 mm, which translates to 450 mm on D7100 (it being a DX sensor camera) The time was about 12:58 p.m. and we were inside a room with a glass door on the right side of the frame in front of camera and a glass window on my left.
The ISO was kept at 1250 and shutter speed was either 1/25 or 1/30 seconds, metering was spot metering on the frame of spectacles worn by Mr. Sunit Sharma.
I found the lens very good in as much as it was sharp, focus was instant, easy to handle, bearable weight and with solid built. The only disadvantage I found was the on zooming in, the lens increases in length (unlike a lens like 200-400 mm f/4) but its not an issue at all.
As Raminder Singh later observed that Nikon could have easily priced the lens at 200K but has chose to keep the MRP at a shade less than 95K is a steal.
Now coming to White Balance thing, The following five pictures were clicked under the same light and other conditions and within a span of few seconds.
The first picture is clicked at 'Auto' WB. The Second is clicked at 'Fluorescent'; the third at 'Shade' fourth at 'Sun' and fifth at 'Cloudy'.
1. As we can see that The Auto was ~AUTO, no drama, no finesse, no overtones.
2. The Fluorescent WB setting made the picture a little cooler and warm tomes are almost missing from the click.
3. Third click is with 'Shade WB' setting and the warm tones, the orange and red shades are more than evident.
4. The most natural shades appeared at "Sun WB" settings. the colour of light in the room and the colour of wall behind was actually as is in the picture.
5. The cloudy settings also had quite warm tones but little lower than as were in "Shade" WB.
These pictures were not exposed to any post processing or photoshop process except for converting them from RAW files to web friendly size and removing noise, which was evident due to High ISO on the DX body.
Hope this will give you an insight on how the White Balance works and will add a new dimension to your clicks this Deepawali.
Happy Deepawali in advance to all the friends.
Wish you Happy Clicking
