My understanding of a "normal" lens as a casual student dipping in and out of books and online courses is that 50mm lenses (as found on 35mm film cameras) replicates the same focused field of view as the human eye. Which also just happens to be approximately 50°. Though it is true that we see a much wider angle than that in our peripheral vision, how much of ...

The thin lens equation is 1/f = 1/do + 1/di, where f = focal length di = image distance = distance from lens to sensor do = object distance = distance from lens to subject. The focal length of a lens is defined by the thin lens equation, and it can be interpreted as a measure of the inverse strength of the lens. If you make a lens's optical surfaces more ...

The specific answer to the core of your Title Question, "the term for the distance", is: Infinity. Infinity is the (imagined) subject distance in front of the optical center of the lens that corresponds to an in-focus image on the sensor when it is spaced behind the lens at the nominal focal length. The engraved "focal length" which appears somewhere on ...

Focal length is the distance between the lens and the sensor when the subject is in focus, not the distance to the subject. The term for the distance to the subject in focus is the focus distance. The zone which is in focus either side (front and back) of the subject is the depth of field. This varies with the aperture - depth of field increases as the ...

Some basic terms for cinematic/video camera movement are: Tilt Pan Zoom Rack focus Pedestal Dolly Truck Most are related to axes, but not strictly so (and in the case of zoom and rack focus, not at all really). So it's not like yaw/pitch/roll directly relate to camera movements. Tilt is rotating the camera in pitch from a fixed point. Pan is rotating ...

Panning is rotation around a vertical axis which causes the field-of-view to move horizontally. This is where the traditional term of panorama comes from. Titling is rotation around a horizontal axis going through the camera perpendicular to the lens which moves the field of view up and down. There is a coined word vertorama which essentially means a ...

I'd call them "portraits" or something like that.

It looks like the term losee is most likely a typo, but for what it is worth, here is the answer that I ended up discovering. The possible file formats were jpeg tiff psd dng And the answer was jpeg.

As you know, digital images are a paint-by-numbers system. This is binary math using only two digits, the zero (0) and the one (1). The word digit is Latin for finger, and its root comes from the fact that we often count using our digits. The bottom line is: a digital image file can contain a googolplex of digits. How nice it would be if we could figure out ...

"Lossy" refers to lossy compression. The most significant format using this is JPEG. Lossy compression is a slight misnomer. What actually happens in JPEG conversion is that the data is slightly modified to facilitate better compression. The actual compression of the modified data is not, itself, lossy ( typically it's Huffman encoding ). The ...

I'm 99.99% sure that this is just a typo for "lossy". I've never heard of the term "losee" and can't find it in search, either. Especially if it just appears in a review question and not in the rest of the text — it's probably just an error. A lossy format, of course, is one which discards (hopefully mostly imperceptible) information in order to achieve a ...

My explanation includes a graphic to hopefully help make it clearer. The bar on the right is the hues. The square to the left contains all of the tones of a particular hue. Any particular tone is described with two dimensions, the vertical dimension (in this representation), sometimes referred to as brightness or value and the horizontal dimension, also ...

Using the term tone as an aspect of the hue and saturation of a color, along with its is more applicable to some of the other visual arts, such as painting. Even there though, the most classic sense of the usage of tonal value refers to the lightness of a color independent of its chromaticity. Please see the link at the bottom of this answer for a very in ...

Traditionally in art, there are several different words used to talk about what we might less precisely all refer to as "color". They are: Hue: this is the property that means the color itself, regardless of how bright, dark, or pure it is. Blue, orange, red, green, purple, yellow — these are hues. This is the position on a color wheel, basically. ...
