Black Hole. 24hour timelapse with webcam | Risto H. Kurppa. How to obtain a greater depth of field in macro photography @ Edu Pérez - Photoblog. One of the most common problems in macro photography is the small depth of field: obtaining a photography where all our scene is focused is not an easy task; when closing the diaphragm is not enough (or convenient), we have to make use of other techniques. The problem The depth of field of a photography is the part of the scene which is on focus: everything behind or in front of that zone is out of focus. The size of this zone depends on three factors: The focal length of our lens: a longer focal length will produce a shallower depth of field.The diaphragm: an open-wide diaphragm will result in a shallow depth of field, too.The distance between the camera and the subject: again, a short distance means an small depth of field.

In macro photography, the distance between the camera and the subject is very small: frequently, between the front of our lens and the insect or the flower that we are trying to photograph there are hardly a few centimeters, sometimes even less.

By David Martin, Jeffrey Martin, and the 360Cities Team Outline Introduction You are probably already familiar with medium of 360 degree panoramic images from either Google Street View or KML PhotoOverlays in Google Earth (from the Gigapxl, Gigapan, or 360Cities layers).

Tools for authoring panoramic images are getting very good, but the process of preparing and presenting such images on the web is still difficult. You can turn on the 360Cities gallery layer in Google Earth to view panoramas from our system. Google Earth Screenshots (click to view larger images) What is a Panoramic Image? A panoramic image is the ultimate wide angle image. Because a panoramic image shows you what the world looks like from a single viewpoint, it is shaped like a sphere.

Color can be defined by particular wavelength(s) of light. A pure color will have one particular wavelength such as 450nm will appear as a vibrant blue. The nm stands for nanometer and is a measure of length. One nanometer is a billionth of a meter. The measurement is for one full light wave length. Humans can see from about 400nm (violet) to 750nm (red). The human eye is not equally sensitive to all colors. The human eye also changes in color sensitivity depending on the ambient light. The eye is most sensitive in the green - yellow portion at around 550nm at night when it is using its rod sensors. So where does the human eye see relative to other wavelengths? Ultraviolet Classifications Your typical infrared enabled digital camera (e.g.

We do have a thermal MIR camera available which can see heat and make non-contact temperature measurements.
