Several types used for everyday purposes such as in kitchens, bathrooms, laboratories, whereas some other type used for the needs of a larger industry.

Buying and selecting digital scales can be a difficult task. The first thing we need to do is determine what items or products that will be weighed. This means we have to have a rough idea of the object with the most severe capacity, and then we also need to know how much detail the size that we need to weigh the object.

Usually each scale weighs up to 3,000 divisions. For example scale 3000 grams in 1 gram will rise gradually, and also scale 6000 grams in 2 grams would rise gradually. This applies to the majority of digital scales but is not a rule like that.

Can anyone recommend a good digital camera for photographing jewellery?

Thank for your help.

The best way to take photos of jewelry for a web site is with a digital SLR and a macro lens. If you are not going to go with a DSLR, almost any point and shoot with a macro mode will serve you well. The thing is, I feel that you need to use the flash to force the aperture to close while still having enough light for an exposure. Many here will tell you different, but follow this advice and see what you think.

Use your macro setting and experiment. Let's say you have a point and shoot camera with macro and a flash on the camera. You might have to go to a manual mode to do this, but...

Put your item on a nice background surface. I like to just put it in a ring box or on some velour. Zoom out at least half-way so that you will be working about a foot away from the ring. Be sure that you get focus confirmation. Shoot a picture USING flash. Check the LCD for the result. If you have overexposed the item, use the EV adjustment to reduce the exposure. For small items, I often find that I need to reduce the exposure by about 1.0 EV. (That's -1.0 EV.) It is better to have the item properly exposed and the background underexposed, so just worry about the jewelry for now. Using a deliberate underexposure will cure the "too shiny" appearance of the stones and metal.

If you know how, you can use either full manual exposure or just Aperture Priority and choose a smaller aperture (larger number) to make the ring show up in better focus.

If you have a DSLR, post your question again stating the kind of camera that you have and the lens that you are using and we will give more details.

If you are doing any image processing at all, such with Photoshop or it's cousins, you can crop the image to 800 pixels by 800 pixels and use Supersize images on eBay. I always use the Picture Pack when I am selling anything of any value.

Check out http://www.members.aol.com/swf08302/heartring.jpg which I did a while ago using a Nikon Coolpix 5400 exactly as described above. I do NOT think this is acceptable, but we decided not to sell the ring anyhow, so I didn't bother to do a better job. It's still better than some I've seen. I don't keep old photos of sold items around, so I don't have much to show you, but at least you know that it's possible to get an acceptable result even without spending huge dollars on your equipment.

The key things to remember are:
-Macro setting
-Zoom out to get about a foot away from your subject
-Use flash
-Try different EV settings and expect that you will end up with a negative EV setting, such as -1.0 EV.

I happen to have some photos from old auctions on an FTP site. I think that these were all taken with a 3 MP Nikon Coolpix 885.

(The patch is about 4 inches long.)

Here are a couple of coin photos done exactly as described, but using a D200:

I did these with my Nikon Coolpix 4600, just to show you what a really inexpensive camera can do. It's a 4 MP camera that I paid about $150 for a couple of years ago.

Here are a couple more auction photos done as described, using a 60 mm macro lens on a DSLR:

If you are interested in a full description of an SLR set-up, post a new question and ask specifically for that information. I'm gathering from the nature of your question that you might be in the point and shoot market.
