Canon Sd880 Is

Buyers tend to look at the camera the size of the image, in particular, the number of megapixels. But how many are really necessary?

Well, it depends on a number of things: if you want to display the image on a computer screen or print, what is its importance, the subject, and how you're boring.

The standard resolution of computer monitors is 72 dpi. This means that you must have 72 pixels per inch of screen width. If you want an image to display 3 "x 2", then that is 216 x 144 pixels (3 x 72 = 216: 2 x 72 = 144).

For an image in a standard blogger blog, just sufficient width of 400 pixels. Even if it is a landscape picture, 600 pixels high, which is still a meager 0.24 megapixels. Adding an image to a text message, which is slightly larger than that. In other words, any mobile phone which has a camera has enough pixels to your blog.

To fill the entire screen, (perhaps for a Powerpoint presentation) the size of the monitor the most common today is 1024 x 600 pixels, which is still only 0.6 mega-pixels.

But if you print a photo 72 dpi, it look terrible. The standard resolution for printing is 300 dpi. A print postcard-size is 6 "x 4", or 1800 x 1200 pixels = 2.16 megapixels. A standard 10 "x 8" print (a slightly smaller than the size of letters) is 3000 x 2400 pixels = 7.2 mega pixels. There is clear that a 10 megapixel camera or 12 will do it comfortably. But an exhibition print size 24 "x 16" would be a huge 7200 x 4800 pixels. This is 34 megapixels.

If you find an affordable 34-megapixel, please let me know. Until someone is one, it is probably best to stick to the print size will not be disappointed.

Fortunately, this is not the last story. You can increase the number of pixels in the image with Photoshop, or with the free program GIMP. It does not give as good results with extra pixels in the camera, but it's better than sticking with enough pixels. The details are a bit fuzzy, however. Even the best algorithms of inflation in the world can not produce information that fell between the cracks into the detector chamber

300 dpi is the norm, but this does not mean it is etched in stone. Some questions for which there are no small details, are within the definition much lower. Sunsets and clouds, or something of the accent, for example. Some, such as water, may even see more clearly lower resolution, since the effect is much more like a soft focus. Print the skin under my eyes at 100 dpi, please!

And they are issues that are much better at 400 dpi or higher resolution. long grass and hair are particularly demanding. Not that they look bad 300 dpi: They look more better at 400 dpi or more. (In the same way that a negative impression of a 35 mm looks good but a negative aspect of a bigger is better. There is a reason Ansel Adams on a simple camera and tripod plate around Yosemite.)

And finally, the question of how annoying you. Some people do not mind blurry prints, as some people do not mind a Wed angle of the horizon of ten degrees. But if you're planning to sell your photos, I suggest you should be more selective about its customers.

So, if your photos are just surfing the web, the number of pixels camera does not really matter. If you only want small prints, camera will be modest. But if you have the ambition to present their work, you want all the pixels you can afford.

How to change the shutter speed on a Canon SD880 to shoot?

I go to a concert on Thursday and I said, it is preferable have a high sensitivity ISO and fast shutter speed. Shutter speed is a Canon SD880 is faster than 1? their website indicates that it can be configured to 1 / 1600. I do not understand how to configure with it. Does anyone know how to adjust the shutter speed 1 / 1600 on a Canon PowerShot!? I looked in the user, but it could have been written for babies … there anything on the shutter speed on it. THANK YOU. If you have any tips on setting more to use for concert photography, it would be great:) I can make shutter speed. so idk … description page website says that you can make the shutter speed 1 / 1600. What does this mean?

You never want to use, 1 / 1600 seconds in a low light situation, because it is very fast shutter speed All photos be a fuzzy mess. The SD880 IS is a compact (fully automatic) camera, so you can not adjust your shutter speed preferred a long shot / exposure between 1 and 15 seconds (1 "-15"). And then he need to mount your camera on a tripod. Able Shutter speed the faster the camera is 1 / 1600 sec, however, can be adjusted manually. The camera uses a very fast speed in a very bright outside (more light than it is outside, the faster the shutter of the camera choose). Use the "Kids & outdoors pets scene mode full light would also apply a fast shutter. In general, little light must use a higher ISO (800, 1600 and above) to get a shutter speed fast enough to handle blurred. Unfortunately because your camera has an image sensor very low, then you have a low capacity of the ISO, ISO 200-400 is the maximum you want to use (even so much noise in these low ISOs). It is also necessary to use a fast lens (one with the iris open) with order to use a shutter speed faster with more ISO. The problem with a compact camera is that it is the smallest and the lack of lenses … Keep away more, more openness is the slowest … the lens is placed. Therefore, due to limitations of your camera … its success will be very limited. But maybe you can try the "night portrait" scene mode (page 54 of your User's Guide) if you can get near the stage. Although I expect that the levels of image noise is very high. Good luck …
