|Leaves in black and white showing Wood effect.|
I took this infrared photo of a weed growing in my flower bed. The image was captured with a Nikon D90 with a standard infrared (720nm) conversion. The day was quite bright so the camera settings were f/4, 1/2500 sec, ISO 200, and -3EV to keep from blowing out the highlights.
The Wood effect which is common in IR photography, made the leaves white. The negative EV made the background black. The camera used the standard LifePixel white balance setting and final WB was established using the Nikon Capture NX2 software. I knew this was going to be a black and white photo so I didn’t perform a channel swap or alter the colors in any way.
|Inverted image after a little clean up.|
The photo was still pretty bright at this point so I used the levels and contrast sliders to improve the tonality. The photo was converted to black and white using the standard Photoshop layer function. After a little cropping sharpening, and contrast adjustment, I got the first photo you see in this article.
I posted this photograph on the Nikonians Infrared forum and one of the members suggested inverting the image to get black leaves on a white background. I had to do a little cleanup after the conversion and adjusted the brightness and contrast to get the second image.
