I was wondering if anyone has had any experience with digital cameras, who would know what to look for in a camera that was to be used to take close-up pictures of small objects, whose primary venue of display will be on the Internet? (Large glossy printed enlargements are not envisioned). I do not want to spend more money than necessary, but also would not want anything which was not able to deliver as good a picture as you can get on a typical good color CRT in today's Internet environment.
Also, there are so many different kinds of memory cards. High speed is not essential but I don't want something which will become obsolete too quickly.

You should email Daniel, or Mirage he has an interest in photography as well as George, another someone! Perhaps Hadrian also, but not for sure, but he takes some great shots for the other thread! They may be able to tell you a little something about that!
-
I get a little lost with digital, I'm more old school. So therefore I wouldn't want to offer any advice as it would be shakey [;)]
Thanks though Karen for the big ups [:X]

If you want extreme close-ups you'll need a camera with macro facility. Olympus do some good ones that are excellent for close-ups, and they're not that expensive.
For display on PC monitors you won't need particularly high res - anything from 2megapix upwards would be sufficient.
It may also be worth considering a tripod of some kind to keep the camera steady. In macro mode even the smallest judder can put the photo out of focus.

Learnt that one the hard way [;)]

If it is top quality high detail you after then you need a camera that can take a micro lens and you will get what you pay for so expect to spend a lot before you see real quality over cheep lenses. Cheep Micro lenses are often disappointing so be warned. If it just good close ups you want then you always use a standard quality lens (even a good zoom 18-70) on a good camera that has high mega pixels 8 and above and then crop your photo in a photo editor. I do this a lot as it reduces the amount of equipment I have to carry. Just remember it’s the result that matters not the way you got the picture.

You probably remembered me saying that I would like to learn more about digital photography hun [:)]
-
Maybe, How are you this afternoon Daniel?
-
I'm good thanks hun, would really like a jam and cheese sandwich now though.
How are you?
-
I am pretty good. Jam and Cheese eh? That is an unuasual combo!
-
Oh jam and cheese is great. I first tried it when I was younger, the cheese I used was edam and it was loooooooverly [:)]
-
I have never tried that it seems different!

"LIDL" sell a microscope with a PC ocular (digital camera which connects to Personal Computer) for about £40.
"Sleepy Lizard" thinks it is a bargain...

SleepyLizard's micrographs using the "LIDL" low budget microscope do suffer from chromatic abberation (colour fringing),
but what do you expect for 40 quid.

That is pretty good detail Robert!
-
I actually think that looks amazing for £40 !!
Thank you Robert

Yes, I agree!

The biggest thing that can be fully imaged with a low power microscope is approximately 3x4mm, e.g ...

Velcro by ROBERT
So if Atomic-S wishes to photograph, say, whole butterflies, (approx. 50x60mm),
then he/she will need a camera with a macro lens, rather than a microscope with a camera attched.
-
Serioulsy excellent pictures..thanks Robert
-
WOW THATS COOL!!! What kind of camera is that?
-
A macro Lens EH? My Camera is definitely out of the running here for sure! tHAT IS SUPER!
-
You can have so much fun with a macro lens, it can make lots of things seem a lot bigger [;)]
-
THey don't make anything like that for a digital camera do they!

Karen,
if your digital camera is an SLR (Single Lens Reflex) type, i.e. with interchangeable lenses, you can buy devices called "extention tubes" which fit between the camera and the lens to produce magnified images.
Typical extention tubes will enable in-camera magnification up to actual size, (1:1).
(The velcro image above is approximately 5x actual size in-camera, 5:1).

MY CAmera is A Fujifilm Digital camera A 400. 4.1 mega pixels! The front pops out when you take a picture..The book says Approx.114 mm to 410 mm,maximum zoom scale: approx. 3.6x..
What is SLR Robert? what does it stand for? Sorry, I missed that.. SIngle lens reflex.. Jeesh I knew I saw it.. Well I don't know if mine is or not!
-
This is an SLR hun

And like Robert said, an SLR stands for Single Lens Reflex

Mine is silver and has a sigle lens that pops out but I can't see where one would attach it to my camera as mine is built in, which that looks like it is also!
-
Is yours something along the lines of this hun?

-
Similar looks right except thatit is 4.1 mega pixels and 4scene modes, 3 optical zoom is the same!MIne has a eyeball in the right hand corner by the words fujifilms. mine says $.1 mega pixels instead!
-
I bought mine about 2 months ago if that.. I think!
-
I seriously doubt that you can put an extra lens on that hun. That's why I love SLR's. You can get a wide range of lenses to fit onto them
-
Yeah I doubt it too!
-
If your camera's lens is NOT interchangable, but has a filter thread around the front, then you can fit a "close-up filter".

This is just like a magnifying glass* which attaches to the front of your camera, and will allow you to photograph objects closer to the lens than would otherwise be the case.
(* You could experiment with holding a magnifying glass between the object and the camera).
-
Thats cool, thanks Robert!
-
I use a Canon EOS IID with a 3X multiplier (extension tube) for wildlife photography. It's got macro facility too - but you're talking serious money.
-
I just have a 200.00 cheeseball fuji Digital!! Camera

Good pic. I actually guessed correctly that it was Velcro, before reading it. I must be smarter than I think.
