Most lenses have a filter thread in the front where you can screw on camera lens filters. These filters cover a range of options, including adding tints or darkening a scene.
If you look, you will often notice that a photo beam detector is being used. Near the door on one side of the store is a light (either a white light and a lens or a low-power laser), and on the other side is a photodetector that can "see" the light. When you cross the beam...
Placing this in the center of the image circle you can see that only a small part of the image projected by the lens actually is captured by the sensor. The smaller sensor basically sees this 300mm lens as a 3200mm lens. This is known as “crop factor”. The smaller the sensor the ...
If you’re going to be photographing in low light or usingdepth of field(DoF), you will need to consider the aperture (or f-stop) of your camera lens. You can calculate this number by dividing the focal length of the lens by the diameter of the opening in the aperture diaphragm. f ...
So far, the only workaround I have found is to keep the AF-ON button pressed (=effectively doing back button focusing) while releasing the shutter. Pumping the button that initiates the AF is also a widely used strategy when (manually) tracking an object. ...
as you get older as the eyes don’t produce as many tears. You can also have issues with objects blending into the background as well as floaters/spots in your vision. Peripheral vision decreases more and more as you age. The way you see colour also changes, as colours become more ...
Only if the solar storm’s magnetic field couples with Earth’s magnetic field do we have a chance to see auroras. AURORA FORECASTS Even the smartest aurora scientists will tell you that predicting the aurora’s presence on any given night is far from a perfect science and includes many ...
So if your lens is 50mm, then shoot at 1/50s or above. If your lens is 100mm, then shoot at 1/100s and above. If your lens is 200mm, then shoot at 1/200s and above. Make sense? The rule isn’t perfect, and I recommend choosing your shutter speed conservatively (a too-fast...
Yes, I guess a RAW workflow would be better suited to landscape photography. The reason I've avoided working with RAW software so far (other than X-RAW) is the Fujifilm simulations. No third party software exactly nails them. I can't say that I'm especially enamored of the in-camera ...
