Mr Motivator Posted February 28, 2005 Report Share Posted February 28, 2005 Oki oki, I have a sony cybershot 5.1mp digi cam, and in the settings you can select it to take pics at 5mp, 3mp and 1mp. When I took a pic on the 5mp setting, appart from it being like 2mb in file size it seemed just as cear as a pic I took in the 1mp setting. Why? Or is it that the bigger the mp, the larger the pic size. A confused, Sam :blink: Quote Link to comment Share on other sites More sharing options...
thesubway Posted February 28, 2005 Report Share Posted February 28, 2005 Isn't it becouse the more mega-pixel the better the image there may be only slight changes in the quality, you can resize the pictures i think on the sony software?.

Tartridge Posted February 28, 2005 Report Share Posted February 28, 2005 Or is it that the bigger the mp, the larger the pic size. Correct. If you resized the 5mp picture to 1mp size, its resolution would be MUCH better, and therefore better quality. Quote Link to comment Share on other sites More sharing options...
Trebor Posted February 28, 2005 Report Share Posted February 28, 2005 Why? Or is it that the bigger the mp, the larger the pic size. I'd guess that the pictures are still on the camera, so it'd be easy to get confused :blink: Once you start zooming in though, you'll see the differences . . . .

Alexx Posted February 28, 2005 Report Share Posted February 28, 2005 Correct. If you resized the 5mp picture to 1mp size, its resolution would be MUCH better, and therefore better quality. ← Technially going from 5mp > 1mp will give you exactly the same res as just taking it at 1mp in the first place. MegaPixels are a physical size constraint, it doesn't reflect on the actual quality of the picture, downsizing from 5mp to 1mp won't give higher rez or quality. 1mp picture = 1 million pixels in the image (so PxK) 5mp picture = 5 million pixels in the image (so 5Px5K) Quote Link to comment Share on other sites More sharing options...
Tartridge Posted February 28, 2005 Report Share Posted February 28, 2005 I was kinda meaning DPI... 1mp picture, say its 1000x1000 pixels, and at standard 72DPI thats, what, 13.9 inches. 5mp picture would be 2236x2236 pixels, so for a 13.9" picture, comes out at 160dpi - much better resolution.

On your screen DPI doesn't mean anything, since your screen is a set DPI (depending on your monitor), so a 10x10px image at 72dpi is shown as actually 10pixels on your screen, but a 10x10px image at 288dpi, is just shown as a 40x40px image also at 72dpi, unless your printing the image the DPI means nothing, higher DPI = higher physical picture size, so, bigger picture.

Tomm Posted February 28, 2005 Report Share Posted February 28, 2005 You are aware that you can get 1MP cameras for like £50? So using your posh Sony 5MP camera to take 1MP pictures is a stupid thing to do... And before anyone says, I'm well aware that the number of (Mega)pixels isn't everything. But if you're only using 1MP, you're seriously wasting your money having a 5MP camera. My (ex) girlfriend used to annoy the hell out of me by using her 3MP camera to take VGA (640x480 = 0.3MP) photos, "because they took up less space on the camera". And she refused to buy another memory stick :blink: Having said that, my camera is only 3MP, and that prints 6x4" (I.e. normal photo size) photos perfectly. At A4 size, you can just about notice the pixelation, but that's OK. The only time I'd really want the extra 2 megapixels is if I wanted to zoom into a picture loads after I'd taken it (I.e. crop loads off it). Then it'd be useful.

Mr Motivator Posted March 1, 2005 Author Report Share Posted March 1, 2005 (edited) (Y) Think I got it now :D I really need to get a new memory stick for it though. Its only a 32mb.. so that means I can take only 12 pictures on it when its at 5mp. 1mp gets me 40 something Sam :ermm: 1gig card :lol:" Edited March 1, 2005 by Sam@SouthTrials Quote Link to comment Share on other sites More sharing options...
Trebor Posted March 2, 2005 Report Share Posted March 2, 2005 1 GIG card :)" If you're seriously considering that, don't, imagine if it broke when on your using it, not only would that be a huge amount of money down the drain, but alot of footage/pictures could be gone, get a few 256's to be on the safe side (Y) Quote Link to comment Share on other sites More sharing options...
Janson Posted March 2, 2005 Report Share Posted March 2, 2005 I use a 512mb one in my Canon Ixus 40. Gives about 250 pictures at 4mpix mode, full quality and resolution. Big card just lets you keep more of the images you take. I can hardly see myself take 250 pictures in one day, but on vacations etc. it can come in handy. Also, big card means I can record 4 minutes of video at 640x480 @ 30fps. Not bad at all for clips. Quote Link to comment Share on other sites More sharing options...

The number of pixels IS the size. Of course the 7mp one is bigger. I swear stupid people shouldn't be allowed nice things. Quote Link to comment Share on other sites More sharing options...

Mike Deere Posted March 2, 2005 Report Share Posted March 2, 2005 Now here's a common mis-conception kids. The number of Mega pixels a camera has, is NOT a good measure of the actual image quality. You're far better off with a smaller CCD that produces a sharper image, than a much larger CCD. Simple as. Quote Link to comment Share on other sites More sharing options...
