How much better quality are the photos from a camera with 7,8, and 12 megapixels?

Callen C

Like I know the statistics of pixels per line and stuff, but how much can you blow these guys up before you can see the difference? Is there a big visual difference between a 7, 8, or 12 megapixel camera? How much visual difference really is there between there 3?

Answer
Megapixels are no indication of quality, they only indicate the size of the file generated.

You could have a 12mp image that looks horrible when enlarged in comparison to a 6 or 8mp image. There are way too many factors in the creation of the images, and megapixels is a relatively minor one.

Ignoring all other variable being equal, a 12mp image is not significantly larger than a 7mp image. If you;ve got an image editing program, create a blank image at the pixel dimensions of each size and compare, you'll see it's not as large as it sounds.

How much any of them can be blown up will depend on the quality of the image taken, all the characteristics of the lens and camera, the post processing, the type of print being made, and the viewing distance of the print. Any easy answer is just a loose guideline.

What is the best digital 12 megapixel camera i can get with these requirements...?

bluthngsx

Under $200 would be great.
It should be able to take pictures in B&W and maybe sepia?
I like to have the different setting for snow, beach, documents, night, portrait.. the usual.

i know i'm picky, but my 12mp Olympus broke and i loved that camera, the only thing i didn't like about it was that it couldn't shoot in black and white or sepia.
please help!

Answer
Leo is right - squashing too many megapixels into the TINY sensor on a P&S camera only makes the quality worse, you get more grain/noise.

6 megapixels is about perfect for a small P&S camera.

About those picture modes, consider this:

the color accent option seems to be a current fad that teenagers are all excited about.
The camera keeps one color and turns everything else black and white.

I would never use such a feature for the following reasons:

⢠You are very limited in what you can do.
⢠The function isn't always reliable or accurate. The camera's idea of "red" might be different to yours. It will often include/exclude areas that you don't want to have included/excluded.
⢠Imagine if you just happened to take your best photo ever, but instead of having a real color photo, you only have some partial b&w thing that might look totally awful. You'd kick yourself.
⢠If you do the "Selective or Partial Desaturation" (as it is called correctly) in post processing, you have much more control over it, and will get a way better result. Plus you can keep your original color version, too.

This also applies to any color effects done in camera like b&w, sepia or color swap - you're better off NOT to. Doing such things on the computer gives you MUCH better control and a much better result.

If you don't have your own image editor, you can go to www.picnik.com and use their effects menu which makes it very easy.

photographers out there, 10 or 12 megapixel camera?

Blessedwom

I am going to buy a Canon Rebel XSI camera but I don't know if I should get 10 or 12 mp? there is a 100 doll difference. I do want to print photos but don't know how large I'll go. Also, should I just get the cheaper one (10mp) and invest in a better lense? I am looking for quality of pictures of course but I am unsure of which lense to buy also! help!
I want to take wedding pictures, senior pics, babies, etc. which lense would you recommend?

Answer
It's not so much printing large pictures but you can crop the picture smaller and still get excellent results.
So get the higher of the two...it's a hundred bucks well spent.

Which lens depends on what you might be doing.
Short zoom is probably best for general use, though I like taking wildlife and find my 70-300 zoom is never off my camera.

Any excuse to show some of my pics...(10.2mp Olympus E-510)

How big can I blow this picture up?

12 megapixel camera how many photos image

Alexandra

I used a Nikon Coolpix L110 digital camera in macro mode. It's a 12.1 megapixel camera with 15x zoom. I was wondering how large I would be able to get a print of this photo with crisp resloution. What's the biggest print I could get?

Answer
If the image is tack sharp and shows NO blur caused by camera movement (and assuming your camera is set to its highest resolution) you should easily be able to make an 11x14 inch print.

However to know for sure, you need to take your image file to the lab and they will be able to tell you straight away what the largest enlargement can be

What is the best digitial camera to get?

(:

I'm getting a new digital camera. I'm 14, a girl, and the budget is not an issue. What's the best digital camera in your opinion? Is the Sony tx1 or the Samsung 12.2 megapixel camera (the one with the screen on the front) any good? Most descriptive and helpful answer gets the points. Please and thank you. (:

Answer
At least 10 - 30 times a day someone on YA asks: "Which one is a good camera to buy?"
A quick search would have given you hundreds of replies, but once again here is my 10 cents on the subject:

Point & Shoot cameras are wonderfully handy because of their small size.
When light conditions are ideal, they even take really nice photos - all of them do.

However, they all DO have limitations - they don't do very well in low light situations (i.e. noisy photos, hard to avoid blur, etc). The little onboard flash is very harsh at close range, and doesn't reach very far.
Many of them have no manual functions, so you are limited to only very basic photos, you can't compensate for unusual situations, or do many fun "tricks" and special effects.
P&S's also suffer from frustrating shutterlag and many of them chew through batteries rather quickly.

However, if you're ok with all those limitations, then go ahead and pick one, most of them (the same type and same price range) are rather similar. Personally I would pick either a Canon or a Nikon, and would certainly stay away from Kodak.

A higher end P&S will give you more manual options and better quality. Many of those even give you the option of adding a proper flash (which makes a big difference to your flash photos).

Don't worry too much about megapixelsâ¦. there is a limit to how many pixels you can squash into a tiny P&S sensor before you actually LOSE quality rather than gain it.
Don't worry about digital zoom, in fact, don't EVER use it. It simply crops away pixels, i.e. destroys information. The only real zoom is optical.

Decide which features are important to you, and look for cameras that have that feature.
Then go compare a few models on www.dpreview.com .

The very best thing you can do for your success is to borrow some books and learn about photography. A bit of knowledge will make a much bigger difference to your photos than your choice of P&S camera can.

For what it's worth - if I was in the market for a P&S camera right now, my choice would be a Canon Powershot SX20 IS http://www.usa.canon.com/consumer/controller?act=ModelInfoAct&fcategoryid=144&modelid=19208

What is the use of 10 or 12 Megapixel photo cameras ?

12 megapixel camera how many photos image

Q. Anyone any idea what the use would be for such a high resolution? Has it many advantages? I am about to buy a new camera and I want to know it it's worthwhile investing in a digital photo camera of 10 or 12 Megapixel.

Answer
For an average user, 10 or 12 MP doesn't make any difference. If you are printing 4x6 or 5x7, you will not see any difference between 4 MP and 40 MP! Mega pixels do not impact colors, contrast and etc. Mega Pixels come to play only when you want to print larger photos. More mega pixels is also good for cropping in photoshop. You you will get better pictures after cropping. For instance, you can select part of a picture, like a person and blow it out and romve everything else from the picture and get a 4x6 or 5x7 print of that person. If you have more mega pixels, you can even blow out the subject more and get a 8x10 or even larger print without loosing any quality!

(Cropping refers to the removal of the outer parts of an image to improve framing, accentuate subject matter or change aspect ratio)

I take better pictures on a camera than my iPhone?

12 megapixel camera how many photos image

I Am Me

I was looking through some pictures..well taking pictires and my camera on my iPhone, it didn't seem to be pretty clear and it didn't look like me. So I took about 2 pictires of my on my 12 megapixel camera and they al looked good. Why is that? When I take a picture on a polarid/ kodak camera I look really better, but in my iohone it looks different. And my iPhone pictures don't look bad but on my camera I can take one photo and look like I do in the mirror. I am a model so I do find this weird.

Answer
Most phones do not have good cameras. I remember a friend told me that there phone did but it wasn't an iPhone. The better the lens, the better the camera. I don't like heavy cameras because I move and ruin the shot. So a light weight camera is the best. Do a comparison on line but I'm sure it will take you some time to do

How do I take pictures/videotape the night sky?

YourGodIsS

I have an Olympus Stylus-9000 12 megapixel camera (nothing fancy, not a professional camera) And I'm really interested in sky watching, but I cant take pictures because its too dark and you cant see anything. So is there some way I can mess with the camera settings to make it see the stars and stuff?

Answer
I'm going to be honest with you, shooting the night sky is not as easy as one might think. There are many factors other than your camera that make a difference.

First off, your eyes are much more sensitive to light than your camera is. While you might think stars are bright, your camera doesn't. Your brain also does a terrific job of separating things that are bright and things that are dark, and tells your eyes to make bright things look darker, and dark things to look brighter, so you end up seeing a balanced photo.

Cameras aren't so smart. Well, not yet at least. Ever wonder why shadows in afternoon sunlight look so much darker on your camera than they did when you saw them with your own eyes? Things that we might not think are very bright or significant make a much bigger difference on a camera. This is especially true when shooting pictures at night. Light sources like city lights and the moon are actually really bright and will hide away the stars from your image.

So, the first thing you need to watch out for when taking starfield photos are other sources of light, especially the moon. The best results are on a new moon. And try to get as far from the city as possible. You'll also need to wait quite a while after dusk.

The other thing is your camera. You're almost definitely going to need to use manual settings on your camera, most cameras don't have a preset for star field photography. If you've ever tried manual settings, you may have discovered the "ISO" menu. A higher ISO is more sensitive to light, and a lower ISO is less sensitive to light. High ISOs are typically better because you can take pictures handheld without shaking, but lower ISOs have a clearer image that doesn't look as grainy (lots of tiny little dots in the picture). One might expect that you should use a high ISO when shooting at night, but it is in fact quite the opposite. High ISOs make dark parts of the image look super-grainy, so your black sky will be littered with tiny dots. To avoid this, you'll need a way to stabilize your camera (a tripod is usually best, but you can get creative) and use a low ISO to keep the dark sky smooth. I'd use ISO 200, but I suggest you don't go higher than ISO 800 if you absolutely need to go higher. Turn off the flash and use a slow shutter speed (15-30 seconds is usually enough, depending on how clear your sky is).

The last thing that can be a problem (if you do everything else right) is your actual camera. Small cameras like yours are great for about 90% of images, but unfortunately starfields may fall under the 10%. Most portable cameras (exceptions include the Fuji X100 and Leica X1) have a really small image sensor, so they don't characterize tiny light sources (stars are basically point sources) very well. I know this isn't what you're going to want to hear, but slide film actually works best for starfield photography. But that isn't saying your camera is incapable, especially if you pay close attention to the light. The most important factor is the light that may be polluting your image. While the camera may be an issue, its not the deciding factor (its almost never the camera's fault, almost always the light you throw at it).

As far as video goes, I have little advice other than to take multiple photos and put them together as a movie. Most of the dazzling starfield videos you see are done this way.


Good luck!
