In a traditional camera, the lens was king. If the lens delivered a decent
image, exactly that image would be recorded on the film. As the original image
size was limited by the film size (35mm having become the standard), you would
then have to enlarge it to get any size of print. If the original was at all
blurred this would be exaggerated by the enlarging process. The more light the
lens let in, the ‘quicker’ it could take an image - hence filter
press supplier expensive traditional cameras had wide lenses. What
electronic cameras have done is to downgrade the importance of the lens.
Computer software can supply the missing light, and sharpen the image. What you
need instead is memory. A 1 megapixel image enlarged to 6x4, is barely
acceptable. Above that size, it is a waste of print, but, funnily enough, can be
viewed at larger sizes on a computer screen with little loss of quality. A 4
megapixel image can be enlarged to A4. So, here are the rules. You will see
that, as with most electronic purchases, it is very important to analyse what
you want to do with the camera. For example I saw a neighbour‘s new system with
which she was so pleased, but I was not impressed. There were so many things
‘wrong‘ with it, in fact, her ‘camera‘ was the primary motivation for writing
this article. The quick answer Hydraulic
Pressure Filter Press is: If you do exactly the opposite to everything in
this article, the result would be you buying the camera she did - designed to be
as small as possible, so, although expensive, it had too little power, too
little memory, an inadequate lens, and fiddly to use. If you want to buy the
right system for you; Don‘t just go out thinking the sales assistants can help
you, they may well have pleasant and helpful manners, but most won‘t know much
about anything, do your research first noting the following pointers: 1 Pixels:
- If all you want to do is to post images on the internet, the pixel count
becomes less important, 3 megapixels is perfect. - If you want to print images
to 6x4 or 8x10, however, go for 4 megapixels at least. - If you have a computer
and are prepared to use photo editing, pay extra for additional pixels, and
don’t bother with the features that replicate the computers ability to
manipulate your photos. - If you will rely on printing your images direct from
the camera, make sure it comes from a manufacturer who links to a good lens
maker (eg Kodak, Canon, Olympus, etc.). 2 Export/Printing: Next, how do you get
your pictures out. There are 2 ways - taking the memory Mechanical
Compress Filter Press out of the camera, and slotting it into a print
device, (either a home printer, card reader or a machine at a photo printers),
or by way of a cable. If you are comfortable with computers, either method is
straight forward. If you want to be able to do this without thinking, make sure
your camera comes with a removable memory card (and upgrade this to the largest
size you can,) and buy one with a docking system. It is worth noting that some
people don’t even have computers, they simply take their storage media to Tesco
or any up-to-date photo processing unit and get their photos printed as they
always have! 3 Power:
