M for Monochrome photography. Monochrome photograph is where the photograph has a single hue. It includes all forms of black & white photos; sepia, cyan, browns and all hues of gray. To do it is black & white.
K for Kit Lens. This is my kit lens that came with my Nikon 5100. I used it for almost 2 years until I got my prime lens. Ever since, I have not touched until today, to take a picture of it. Nikon is my first DSLR and I didn't know what to expect. I started out with a kit lens and is a great lens for first time DSLR users. It is also a great lens for everyday photography. I use my DSLR mostly for food photography with prime lens. If one uses DSLR for everyday photography, it is good one to have in the collection of lenses.
There are many options for J. J for jump, jewelry, joint, junk, jugs and JPEG. Since the theme is photography, I considered J for JPEG. JPEG is a format to compress and store digital images. Then, I didn't have an appropriate photo to go with the post. This morning while drafting the post, I changed it to J for j instead, the alphabet 'j'.
I for ISO. ISO is one of the elements of exposure triangle. ISO stands of International Standards Organization, which sets the sensitivity of sensors on digital camera. Sensitivity of the image sensor depends on the ISO number and smaller the number, less sensitive the sensor is. The lowest number is 100 and it could go up as high as infinity. The highest ISO on a camera varies from camera to camera.
The rule of thumb is to keep the ISO low but in low light conditions, in indoor sporting events and in low light conditions when the photo is taken with out a tripod, ISO comes to recuse to well expose the photo. Also, ISO is used when freezing time/motion because the shutter is fast, resulting in less light going into camera. In such cases wider aperture and/or ISO are adjusted to well expose the photo. The drawback of high ISO is that the photo gets noisy as the ISO increases. One must have noticed, often times night pictures usually tend to have a grainy finish. That is the noise due to high ISO.
Today's photo was in a subway station where lighting was low. I didn't have a tripod and had to use a fast shutter to avoid a shake. ISO came to my rescue. Settings of the photo - ISO 12800 (very high ISO number), Shutter Speed - 1/100sec, Aperture - f/2.8. Here are high ISO pictures from the archives.
