Still working on my Anth paper, I should have it done by tomorrow.
Ok, photography tip for the night. Aperture, which is as I described before, how open the lens is to allowing in light (remember the eye example, your pupils). In photography, the aperture is measured by f-stops. The lower the f-stop, the wider the lens can open and let in more light, and vice versa. Lenses themselves are measured in f-stops by their largest f-stop. For example, I have a 50mm f1.8 lens and a 18-55mm f3.5-4 lens. The 50mm f1.8 lens has a larger maximum opening over the 18-55mm.
The other important thing to know about apertures is how they work with focusing on a subject. The larger the aperture (smaller the f-stop), whatever you have focused on in the foreground will be in focus, while your background will be more out of focus. The smaller your aperture gets, the more in focus your whole picture becomes. So depending on what you're shooting, you will want to choose how you want your exposure to comes out.
Next time I do my photography tips, I will discuss shutter speed.
Tonight's photo is an HDR of the Beverly dunes. Hope you like it!
