- Please HELP~
Looking on several page of commons about Photography, I see that the level is really hight compare to my knowledge, also, seems need to set up a "List of Photographic terms" (for dumbies) : what means "close-ups of 1:1" ? Difference between Zoom, optical zoom, and digital zoom ? "point-and-shoot" camera ? "bridge-type" camera ? macro ? DSLR ? Compact ? Lens ? extension rings ? sharpness ? with definition in basic english (most of us are not Native English).
Please provide :
- a definition allowing to understand what we talk about (a link toward wikipedia is welcome);
- an explanation "why/when this is important in photography", and what is need to get a good result on this aspect.
Note that this would be better write in basic English : most of us are not Native English speaker, and not native photographer ;) 18.104.22.168 10:48, 16 March 2008 (UTC)
(Lis to expand)
- Angle of view :
- Not a correct term.
- Blur : an image is "blur" when it is not display clearly (ex: the cirle is clear on the left, blur on the right ). To avoid blur and get clear images, it is need to : a/ make a good focus ; b/ have a correct lens .
- Camera, "point-and-shoot" camera :
- A simple camera, that is fully automatic. It does all the settings. As you have no controls it can only be used in good light.
- Camera, "bridge-type" camera :
- A new term. It is a camera with some controls, and an automatic mode. You cannot change the lens. There is a view finder but it is an electronic screen. The camera is very flexible and good value for money.
- Camera, DSLR camera :
- Digital SLR (Single Lens Reflex). This is like a film camera, but instead of a film, there is an electronic sensor. It has a view finder. When you look through the view finder, a mirror lets you see through the taking lens. When you lake a photograph the mirror moves out of the way. You can buy extra lenses to fit onto a DSLR. They can be very expensive. These lenses let you take photographs in very poor light, and very difficult situations, such as taking photographs of fast cars or sportsmen.
- Camera, Compact camera :
- A compact camera is a simple camera. It is easy to use and to carry. A Point and Shoot camera is a compact camera but you can get compact cameras that have extra controls that can be used in poor light.
- "close-ups of 1:1" :
- Don't bother with this one- it is not a simple term
- Focus :
- To focus, usually done automatically, to focus means to adjust the lens so your photograph is sharp.
- In Focus: |the picture is sharp
- To focus on: Choose the part of the photo gragh you are interested in. To choose the part of the photograph you want to be sharp.
- Focal length :
- A way of describing the properties of the lens. In the past, it refered to the way the lens was made. Now we saw that a wide angle lens has a focal length of 35mm or less, a standard lens has focal length of 55mm, a portrait lens has a focal length of 90mm (this is also called a medium zoom). A zoom lens will have a focal length of over 135mm. A 300m lens is a zoom lens.
Today all cameras allow you to change the focal length you are using. A second meaning of zoom, is to change the focal length. You say you are zooming in to 300mm, and zooming out to 35mm. The reason for this is historic.
- Field :
- Incorrect term
- Macro :
- take a macro picture is to take a picture of small object from a distance of 5cm or less.
- modern digital cameras have a macro mode. Thisw is for photgraphs taken closer than 1 metre.
- Lens (w, w2): the lens or set of lens make convert light toward the camera eyes. The quality of the lens allow to have clear image instead of ( ex: Good lens on the left, bad one on the right : )
- Extension rings :
- used on digital SLRs for macro photographs
- sharpness :.
- Incorrect term
- Zoom : it's the ability to show you things in bigger
- explained above two different meanings.
- Zoom, optical zoom and digital zoom
- optical zoom is the zoom ability by the Lens.
- poor English
- POV For a digital camera and Macro photos this "optical zoom" is the only important one, since the digital zoom is simply "cropping" the image to display a part in full screen. The digital zoom imply lost of quality in the produced image file, while the optical zoom doesn't.
- digital zoom, selects only the centre of the image, which makes it appear if it was taken with a lens of a greater zoom. It does this by cropping. If you are saving the photograph at the cameras maximum sensitivity- (12M on a 12M camera) see Megapixel- then there is a loss of quality. If you are saving your photographs at a reduced sensitivity (3M on 12M), then there is no loss of quality. Photographers who upload their photographs onto Wikipedia rarely work at 12M, so it is not a problem.
- optical zoom is the zoom ability by the Lens.
Here a few ideas to start you off. You should not try to over simplify technical terms unless you know who you are talking to, because clarity and meaning is lost. I would not use any of these definition on a page, with out editing many times. I need to target the simple english accurately for that page- it is far harder to write than English.

- All the fields display on this page : this page
- I am happy to help. To get the level right, I must see the page you are writing. Can you give me the link to the page on simple English wikipedia. Can you give me a link to your talk page on simple English wikipedia, please. It is easier to explain with the help of a simple diagram. Some words in the list are very new, some are words grand father used to use.

- I think first work on commons, so Just complete and expand the list on the top. Add image like I did, I think I will later put all the list into a gallery [ Image | word:definition + context. ] to be more friendly. You can write to my IP talk_page, my IP is stable. 22.214.171.124 14:29, 16 March 2008 (UTC)
Sorry to say, but autofocus is only usably in problemless situations. It doesn't work well in short distances, not through glas, not in mirrors, not under water, not in good distances using big teles, not in hurry (snapshoots). Working with Nikon FE I had never problems, with a compakt digi I get them allways for it doesn't have manual focus. AF allways sets focus to the far background, never to a near subject. It sets focus to a mirror, not to the subject shown in the mirror. It sets focus to a window, never to the subject outside seen through the window. And it needs too long time to set focus, than it could be good for a fast snapshoot. Therefore beginners will have les problems to learn to set manual precise focus, than to learn all these bloody tricks, which are necessary for working with AF.
Sorry fo my bad english, I hope, that nevertheless you could understand, what I mean.
This is the begin of a German version of that project-side - sorry, I don't know, where to depose it:
Versuch einer einfachen deutschen Version
Angle of view: Blick-/Aufnahmewinkel
Ein von manchen Objektiv-Herstellern benutzter Begriff, meist wird „Sichtfeld“ benutzt. Gemeint ist der vom Objektiv abgedeckte Bereich in Grad angegeben. Ein 12 mm Weitwinkel mag eine Öffnung von 120° haben, ein 300mm Tele weniger als 35°
Unscharf, verschwommen werden Bilder durch mangelnde Genauigkeit bei der Entfernungseinstellung und durch Bewegung.
DSLR camera Digitale Spiegelreflexkamera
Sucherdisplay zueigt über Spiegel den Blick durchs Objektiv. Handhabung wie mit Film.
Compact camera: Kompaktkamera
Vollautomatisch, daher schwer zu kontrollieren. Vorteil: geringes Gewicht, geringe Größe, geringer Preis, Nachteil: geringes Leistungsspektrum.
A new term. It is a camera with some controls, and an automatic mode. You cannot change the lens. There is a view finder but it is an electronic screen. The camera is very flexible and generally good value for money.
Close-ups of 1:1 Nahbereich
Eine 1:1 Nahaufnahme bildset in Originalgröße auf Film oder Sensor ab, Aufnahmeentfernung = Abbildungsentfernung = 2 fache Brennweite.
Oft auch gebraucht für Aufnahmen, bei denen die Originalgröße erst durch Verrgrößerung erreicht wird.
Focus: Fokus, Brennweite
to focus: fokussieren, scharfstellen
Entfernung scharf auf das Sujet einstellen
Bild ist scharf
Out of Focus
unscharfes Bild oder Hauptmotiv
To focus on
Scharfstellen auf (das Hauptmotiv)
