What do the curving lines on a weather map indicate?
Usually they are lines of iso-density - or equal pressure. Thus the closer they are, the harder the wind.
How is an astronomical unit defined?
An "astronomical unit" is a unit of distance/length that is the mean distance between the center of the Sun and the center of the Earth.It is an ISO standard with the value defined as 149,597,870,700 metres (92,955,807.273 mi) exactly. It is given the symbol "AU", while the astronomical constant (whose value is one astronomical unit) is given the symbol "A".
How do you use an Olympus XA?
Set the aperture to 5.6. Set the focus to 8 feet. The camera will vary the shutter speed for the best exposure it can manage and the camera is then basically equivalent to a settingless point and shoot camera. It's much better than that though. The rangefinder double imaging is bright for such a small package and when looking through the viewfinder, one can move the focus control and align the two images for sharp images at any selected distance. It is an "aperture priority" camera. That is, it allows the user to set the aperture (how wide the lens internal mechanism opens to let light in) and it controls the shutter speed (how long the light is allowed to shine on the film) using it's internal metering. The meter in the viewfinder indicates the shutter speed being selected by the camera and shows changes in the selected shutter speed as the operator makes changes to the aperture. Many considerations go into setting an optimal aperture/shutter speed combination. Handheld, poor results will be obtained when the speed is slower than 1/60 to 1/30 of a second. Stand the camera on something or attach it to a tripod for slower exposures. Freezing action requires a fast shutter speed. Aperture opening effects something called depth of field. The higher the aperture number you set, the smaller the opening or amount of light allowed in, requiring longer exposures, so also sometimes requiring a tripod for best results, but also giving greatest depth of field so that objects in foreground and background stay more sharply focused. Setting a smaller aperture number lets in more light, and with shutter speed increasing to compensate, makes it easier to take hand held shoots. But with this also comes a reduction in depth of field. Then you need to carefully select the object or area on which to focus the camera. A good general rule is about one quarter of the way into the scene in which you want both foreground and background to be in focus, but be aware, that as the aperture opens wider, this foreground/background range is reduced, so, if objects are to far apart, in distance from the camera, not from each other, the aperture opening imposes physical limits on sharp focus (reduces the depth of field) so even when a good focus point is selected and achieved, some foreground and background will end up out of focus. You can study general photo guides to see these effects, but you won't truly gain an appreciation of your camera until you've done a little experimentation yourself. You'll find out what your depth of field limits are at various apertures, an what shutter speeds best suit various actions and at what speeds you can hold the camera without blurring the image through your own motion. Then there's film speed. At the beach on a bright day you'll get to much light and slightly blue images if you use a high ISO film 400 or more, 100 works best and 200 is good too. Indoors with flash though, you don't get a lot from the three available flash models (A1L lithium, A11 single AA battery, and A16 takes two AA batteries or just stores a larger charge from one battery - I can't recall and don't want to go look - so a 400 speed helps out a lot. The highest ISO setting is 800 but it works well with ISO 1000 speed film and can take great handheld shoots in doors - might be very useful if at a wedding or child's delivery, where flash use might be prohibited The A1L flash is sold as non-serviceable when the battery quits but there are screws under the rubber pad that cushions the flash to camera body mount. If you or someone you know can handle a soldering iron, a two cell lithium can be purchased, removed from it's plastic body and soldered in place of the two spent cells. And speaking of batteries, the camera won't work without one. A little button cell underneath the coin screwed cap on the bottom. I don't shoot any 35mm these days, all digital, but when I did, I had a large Minolta system and some Canon odds and ends. Thinking about shooting and what to take or to take a camera at all, given that I had to be able to travel very light sometimes, could always be an issue. While the XA is nowhere near as flexible as a full SLR system, it is so much more compact and required little thought as to what I might have to leave behind for having to pack it, fit nicely in the red leather magnetic catch XA case on my belt, that it went far more places than any of my other equipment and is the one camera I used to take most of my pictures. Enjoy.
What is DIN and ASA?
asa is the english-speaking world's way of stating the speed rating of film;it is effectively the same as iso. Din is a parallel scale, but with different numbering.
What is the iso code?
The International Standards Organisation code (ISO) was developed to consolidate the ASA/DIN system to rate the relative speed of various films. ISO 400 film is faster than ISO 100 film, for example, making it better for low-light or fast action photos
What does the ISO or ASA of a film indicate?
ASA acronym for American Standards Association - hence ASA400 on films is the standard film speed of 400. ISO is International Standards Organization. the two values are identical, for once there is no separate ( Metric) or different European film standard. The Germans do use the DIN ( German Industrial Norms) standards this is such that that- DIN 27 is equivalent to ASA 400. ASA and DIN are the only common film standards used today. There you have it. Get yourself a Photometer and the meanings of the various scales will be self-evident. Besides you can learn much about differing exposure values- for nearly every potential shot there are more than one possible (answers) so there are considerable variables around. Experiment!
Sensitivity of film emulsion is indicated by?
It used to be the ASA rating, but now its the ISO rating, the higher the number, the more sensitive the film is. e.g. 100 for daylight 400 for nightlight as an example.
What is the difference between COPC and ISO?
all
Difference between iso 9000 and 14000?
The main difference between ISO 9001 and 14001 is that ISO 9001 is based on Quality management system. It tells the client that the Organization has systems, processes in place to ensure a quality product and service. But ISO 14001 is an environmental management systems standard. It is your easy way to improve your business, meet and regulate statutory requirements and find the best balance between benefiting our society and environment while meeting the financial needs of your business.
What is the difference between iso-heet and heet?
The ISO heet contains isopropyl alcohol and the other contains methyl alcohol
What ISO to set when using film ISO 800?
800
How many pictures will a 400 ISO film in a camera take?
Depends on the film size. The standard sizes are 24 and 36 pictures for 35mm film, or between 8 and 12 pictures for 120 format film, depending on the particular camera. The ISO is a light sensitivity rating, and does not affect the number of pictures on the film.
What is the difference between isotopes and iso bars?
Hello! :D I bet you were expecting an answer huh?
What is iso in photography?
ISO was originally a measure of the sensitivity of photographic film to light. ISO is measured in increments such as 100, 200 400 and 800. As the ISO number of the film increases the film takes better pictures in lower light however the images will be more grainy. The convention has carried over to digital cameras with the same relationship between sensitivity to light and image quality.
What is camera film speed?
It's how sensitive the film is to the light. Which is measured in ISO. If you use a film camera. The film box should say what ISO it is. If you have a digital camera, you can adjust it in certain modes in the menu. For more details you can check out http://www.geofflawrence.com/photography_tutorial_ISO_film_speed.htm
