Photography: remote shutter release with gPhoto2

gphoto2

In today's tutorial we see some small function gPhoto2, a program command-line oriented * NIX systems which in addition to other functions, allows us to access some of the functionality "hidden" (or non-advertised) of our cameras.

It should be stated at the outset that not all cameras are supported. The complete list is available on the manuale online application.

The operation is very simple. Configure the camera (io face you Canon EOS 20d) so that the USB connection is of type PTP (under the menu "Communication" - "PTP").

Photography: techniques for the reduction of “Digital Noise”

noise

In today's tutorial we talk about photography. How many times has it happened to take pictures, affect them on the display of the camera and see them in good condition, then download them on the computer and realize the presence of the noise in the picture.

The digital noise present in the photo is the deterioration which can range from small disturbance barely visible, the disturbo "a puntini" very annoying to see as we shall see in the next image which shows how the quality of the image may change, changing the ISO.
