I would go with "motion blur trails", or "motion blur light trails". Light trails in general are the lines produced when an object moves during a long exposure — see How to shoot light trail photos with iPhone? and also When should you use a normal flash vs a second-curtain flash? In this case, of course, the object that moves is the camera, which from a ...

These are light trails, produced due to long exposure during motion of light.

Would this be considered bokeh or does a term even exist for this? I agree with Romeo Ninov's comment: this is plain old motion blur. You could call it "light trails" to make it clear that it's something you're doing on purpose, but photos of light trails are generally created by having the lights move rather than the camera. Bokeh refers to the way ...

This is just a visualisation. The colours in the diagram do not represent the real colours of the noted wavelengths (what you see is dependent on the capabilities and calibration of your monitor anyway), but are chosen to give you an idea where the different colours rougly lie.

The colors on the diagram are just meant to give you an idea of the color space. You could say that the sRGB space is "shifted" to be larger in order to create the illustration.

Sorry, you're way off. :-) Your digital camera only has one base ISO value. The base ISO is the single ISO setting at which your sensor/processing pipeline produces its best signal-to-noise ratio. The base ISO is typically the minimum ISO value which can be selected numerically. (ISO settings below the base ISO are usually marked PULL or LO to avoid any ...

Simply point out a thumb and check its shadow over the palm of your other hand. If the shadow is very sharp, the light is harsh. If diffused, the light is soft. Further, you can safely assume the light from a small source will be always hard compared to light from a huge lighting source. Another thing would be, the far away the light source(even) if its ...

I think that a photograph to be classified as fine art must awaken a deep emotion in the heart and mind of the observer. It must move us. The emotion could be love, pity, tenderness, joy, admiration, awe, etc. Or the emotion could be contempt,hatred, fear,indignation etc. The deeper the emotion or the impact that the image awakens in the observer the ...

Matt Grum's answer is the golden ticket answer. That rule of thumb method will work most of the time, but eyes work differently to photographs, and sometimes our eyes adapt to the light and we can't make out the shadows as definitely as they would be represented in a photograph. Here are a couple more tangible approaches that I use. For digital photography ...
