Children, are by nature, inquisitive. They’re curious about everything and are often not afraid to ask… and ask… and ask! That’s why children learn so quickly. Adults, on the other hand, are afraid to speak up and ask questions especially if they think that asking them will put them in the spotlight and makes them look stupid. Thanks to WikiAnswer. Now, we can anonymously ask that “dumb” question that we were meaning to ask our friends, colleagues or teachers.

So here are some of the photography-related questions and answers that I found really interesting at WikiAnswers. Let’s revisit some of the most basic facts and a little bit of history relating to Photography. Maybe you already knew most of the things asked here. But there could be one or two more items which you have never heard of, until now. So let’s have a Q&A the wiki way!

Photography questions 01- What equipment is needed to be a photographer?

Answer: All you REALLY need is a good camera, and of course talent (creativity, an eye for composition of photographs, imagination etc.). As for the rest of it… additional lenses, backgrounds, additional lighting etc… they are not absolutely necessary. I have shot over 350 weddings and I personally don’t use extra lighting, and I rarely use anything other than “environmental” (available) backgrounds.

Photography questions 02- How do you convert pixels into centimeters?

Answer: In truth, you don’t convert pixels to cm. There is a little more information that is needed and without knowing exactly what it is that you want to do, it is difficult to address this completely.

A pixel is one of the colored dots on your computer screen that makes up both images and text (as well as all of the blank areas in between them). Most computer screens display either 72 or 96 pixels per inch. Most printing is based on 240 or 300 pixels per inch.

If you are asking about printing: If you want to make a 4 x 6 inch print on a 300 DPI (Dot Per Inch) printer you need your file to contain 1200 x 1800 pixels. An 8 x10 will have to be 2400 x 3000 pixels. In reality, most comsumer printing systems will handle this conversion for you. You just tell the software what size print you want to make the software will “resize” your image to the correct dimensions.

I will leave the inch to cm conversion to you!

Photography questions 03- Will Canon 35mm camera lenses fit a new Canon SLR digital camera?

Answer: Absolutely! The only trouble I have had is with a 2X converter and a 400mm lens. It would not auto focus or stop down. I still got an OK photo of the moon. I migrated ALL my lenses successfully. I think film lenses work on digital. Digital do not work on film. Why not? Due to the .625 smaller area covered by the lens. They will not even mount.

The answer above is right, but if you have any troubles with canon and canon lenses just feel free to contact Canon Support Team. Visit canon’s official website and there you’ll be able to find a link to their customer support.

Photography questions 04- Is there a way to fix blurry pictures with photoshop?

Answer: There are a couple of ways to “sharpen” semi-blurry images. You won’t be able to completely make sharp images out of out-of-focus images, but you can try.

1. Under “FILTERS” you can go down to “SHARPEN” and select “UNSHARP MASK” this will pop up a new window. Use the slider to desired effect.

2. You can push the letter “R” on your keboard and it will select a tool on your tool palette that looks like a water drop. If you click and hold this button you will get a couple other tools to choose from, one of which is the “SHARPEN” tool. Use this tool to sharpen specific areas of the blurry image. If you’re in Photshop 7.0, your strenght and brush sizes for this tool will be docked at the top of your window.

Good luck!

Photography questions 05- What does ISO stand for in cameras?

Answer: ISO stands for “International Organization for Standardization” and is taken from the Greek word “isos”, meaning equal. See www.iso.org. ISO has replaced the older ASA designation.

As for how it relates to film, it is an indicator of the film’s sensitivity to light. Light sensitive crystals are an all or nothing proposition. They either react and are subsequently developed, or they do not, and the speed at which they react is the same for any given film. It is more a function of size, but speed is how it’s described. The increase in speed is a result of larger crystals since they are able to react more to light than smaller ones. If this is difficult to grasp, think of them as tiny buckets gathering light. Larger ones gather more, thus producing more image in the same length of fixed time. However, a noticeable increase in the graininess of the image is usually associated with fast film. It is safe to say that doubling the number 400 vs 200) means the film is twice as “fast”.

Photography questions 06 – What is the 2257 compliance statement?

Answer: US Code, Title 18, Part I requires that those producing visual depictions of sexually explicit conduct must maintain record of each performer including their name, age, maiden name, etc.

In other words, the federal government requires that anyone producing pornographic material, must verify the names and ages of their performers and keep a record of that proof.

Photography questions 07 – What does entry level SLR digital camera mean?

Answer:Whether in reference to a digital SLR or to any other product, “entry level” means “made for those who want that category of product, but who do not want or need the advanced features that command a high price.” An “entry level” product is a serviceable “no-frills” model that gets you started in a category for a low price.

Entry level is defined by both price and features. Some advanced DSLR units cost $8000 or more. Without intending either to recommend any specific cameras or to condemn any by omission, I will mention, just as examples, that for about $550, shutterbugs can have a no-frills entry level Nikon D40x or, for about $400, an entry level Pentax K1000D Super.

Canon, Nikon, Olympus, and Pentax are among the major companies that offer entry level DSLRs.

Photography questions 08- Who took the very first photograph?

Answer: Giovanni Battista della Porta’s Magiœ Naturalis Another Answer: Joseph Nicéphore Niépce did, in 1827. Giovanni Battista della Porta in his great work Magiœ Naturalis of 1558 does lay some emphasis on the use of the camera obscura (literally dark room in Latin), a tent or room with a small hole in one wall which optically projects an upside-down image of the scene outside to the opposite wall (all modern photographic cameras are simply small camera obscuras), but della Porta considered the camera obscura primarily an instrument of entertainment, and certainly did not invent chemical photography. That had to wait nearly three more centuries.

Photography questions 09- What distance does the mm represent on a lens?

Answer: Lenses are measured by their diameter in millimeter (mm), which is used to designate the focal length of the lens with smaller number representing lesser magnification and great field of view.

Photography questions 10- Is Nikon better than Canon?

Answer:It is not really possible to come down on one side or another – Nikon and Canon both make wonderful DSLR cameras; one only has to see press/sport photographers to see how Nikon and Canon dominate professional DSLR. Most pro-photographers will stick with what they are comfortable with; they know they wont go far wrong with either Nikon or Canon. I tried both Nikon and Canon DSLR and chose Nikon – thought the images were slightly better on the Nikon and the Nikon felt slightly more “familiar”.

Photography questions 11- What is the difference between higher mega pixel number vs lower mega pixel digital cameras?

Answer: Higher mega pixel cameras offer the ability to print larger images.

For example a 6mp camera offers a resolution of 3000 x 2000 pixels. If you allow 300dpi (dots per inch) for print quality, this would give you a print of approx 10 in x 7 in. 3000 divided by 300 = 10, 2000 divided by 300 = approx 7

A 3.1mp camera offers a resolution of 2048 x 1536 pixels which gives a print size of 7in x 5in

You can make bigger images, but you would need to accept that you would lower the quality of the image.

Photography questions 12- What is the best method for photographing ghosts?

Answer: There is no way, they do not exist.

The Invention of photography was the merging of what two things?

Storytelling and Chemistry

Photography questions 13- Why are your eyes red in pictures?

Answer: You are actually seeing images of the retina, the layer of cells at the back of the eye. There are many blood vessels in that part of the eye, as well as a very high concentration of light receptor cells.

Photography questions 14 – What form of measurement do you use to measure a photo?

Answer: pixels, mega-bites, or inches on a larger scale

Photography questions 15- . What is photojournalism?

Answer:Photojournalism is taking photos of events, such as war, and using the photos to tell the story. They sometimes add text, such as captions with the photos, but the photos are basically what tell the story.

Photography questions 16- What makes a light soft?

Answer: Size matters! This is what makes a light soft. On an overcast day the light is very soft because the source is the entire sky. On a sunny day, the light is hard because the source is a tiny spot away in the distance.

A small light source like a flashgun is hard, but if you bounce the light off a wall or ceiling, then the lit area becomes the light source and, being large, makes the light soft.
