Nikon D300 Infrared Photography Tests
DIMi takes the D300 digital camera out to shoot infrared landscape images and we see how it goes.
As you know by now, I love infrared photography. So we make sure we put every camera that comes through here for testing through an infrared test. This time we had three cameras with us, the Nikon D300 being one of them.
I must say that the D300 is a simply lovely camera and is almost enough to make this little Canon user consider switching. It handles brilliantly and the images are, straight from the camera, simply stunning. But how does it handle IR?
As is usual for our tests we used a Hoya R72 filter and a solid Manfrotto tripod.
An image from the red channel and a 100% section from the middle of the image.
We started off with trying to zero in on the correct exposure. So we started at 100ISO, f2.8 and 4 seconds.
This is clearly under exposed.
Going to 8 seconds get all the channels off the underexposure blockup point, and so you could work with this image but to minimize noise we want the histogram humps up the top of the histogram.
15 seconds is about right for the red channel if we are converting to monochrome from a single chanel.
Going to 30 seconds is over exposure for the red channel, but is still a bit low for the green and blue.
From these I have prepared the best image I can from the green and from the red channel. There is not much to pick between them.
The shots below were taken on another day at another location in stronger light.
This is the exposure that gives the best red channel: original and after mono conversion from red channel and then levels.
This is the exposure that gives the best green channel: original and after mono conversion from green channel and then levels.
This is the exposure that gives the best blue channel: original and after mono conversion from blue channel and then levels.
Interesting note: The AF-S NIKKOR 24-70mm f/2.8G ED we have been using exhibits a subtle hotspot, but only in the blue channel.
If you are in the US and want to buy a Nikon D300 I can recommend B&H Photo in NY.
