make certain digital pictures smaller resolution??

Question

ok. im looking into buying a new camera. im sick of the point and shoot style, even though they are really nice. i want a DSLR, or SLR, or w/e its called. only thing, i wanna be able to take pictures for facebook, and the max resolution to upload pics on is 4 MB. however, i really want a camera with 10 MP, so i can blow up certain pictures. so, if i get a SLR camera with high quality, i think through doing research i saw that this one canon digital rebel XTi could go up to 30 MB, could i later get some converter on my computer to copy the pictures i want (so i can keep the original quality size), and then make those smaller for facebook/myspace. please help, thx. OHH also, if u have any recommendations of SLR cameras, or DSLR (someone correct me w/ the difference between these two), please feel free to comment. thx again.

Answer 1

SLR = Single Lens Reflex ... means the film kind that aren't point and shoot.
DSLR= Digital Single Lens Reflex ... means the digital equivalent of above.

You can download free programs to resize and resample photo's to a smaller file size. That way you can keep the original larger photo, and also have a smaller one for email, myspace, etc. Irfanview is one, and there are many more. Whatever photo editing software comes with your camera when you get it iwll probably do it as well.

For a DSLR, go with a Canon or a Nikon, and do your research so you get exactly what you are looking for.

SLR cameras have lenses that you can remove & replace with other kinds of lenses. This makes them a lot more flexible than point & shoot cameras. They are also more responsive, and they produce better image quality. They are also a lot more expensive (but you get what you pay for.)
The D in DSLR simply stands for Digital.
The Canon XTi is a very nice dSLR camera. It's a very popular choice, and for good reason.
It has 'just' 10 magepixels, but that's enough for small posters. Besides, it will blow any 10 megapixel point & shoot camera out of the water.
When it comes to resizing pictures for the internet, you can run the files from ANY digital camera through an image editor to make copies of your images as smaller jpg files. You'd use the originals for prints and the small versions for the internet. This works for digital point & shoot cameras, too.
Before you spend a small fortune on a dSLR, please make sure that you know what you're getting into. Most people end up getting two or even more lenses. This adds to the cost and it also means you have to drag a camera bag around.
Also, dSLR cameras can't use the LCD screen to compose shots (well, some of them can but not the XTi), and dSLR cameras can't shoot video - only still pictures.
I use a dSLR myself and I wouldn't go back to a point & shoot... but they're not the best choice for everyone.

Yes they are. Your iPod uses much lower resolution images (they are automatically re-sized when being moved to your iPod is all I can guess) You never told us how you lost the originals. This is a good reason to always back up all your images on to a CD or DVD. You have what you have and there is nothing you can do to get better resolution.
