Default Taking pics of coins

I need to take close up pics of rare coins Silver, Gold and Copper...right now I am using an old Sony Mactiva on a copy stand...I am not satisfied with the results which are not consistant..can't find the proper lighting to bring out the true colors of the coin....I use natural light by a window.. most of the time..when it is a bright sunny day my pics come out satisfactory..but on days when it is cloudy the colors are all off...
Looking for a new camera , lighting, equipment etc..that will give me consistency in the pictures and nice quality......if this comes out here is a sample of a recent pic..coin in person is closer to white in color.. this pic is too blue....

Any help would be appreciated

You could set up a consistant light source and then balance the color using a program. I applied some red and yellow to your coin picture to get the truer silver white color you were looking for.

Default Re: Taking pics of coins

I'm not a serious coin collector, but I did some of that as a kid. My true photography love, however, is close up photography. I picked up digital photography about 15 months ago, and I am just beginning to explore digital close up photography.

The two images below are my first stab at it. My camera is the Olympus E-20 and my lighting is nothing more than two 60-watt household incandescent bulbs. The white point of the scene is set using a white card and locking the camera's "read" of the card. Then for all exposures, I'm good-to-go.

As I say, I'm just beginning to explore digital close up photography, but so far, I find it easier than using film; no worrying about film reciprocity and trying to match the scene's white point using filters.

It sounds like you have a case for a macro flash-ring or whatever they are called. I've never used one but that should give you the good light and cnsistency you are after.

Unfortunately they don't come very cheap because they are fairly specialised bits of kit, and you'd need a camera that accepts them. It is basically a circle of light that screws onto the end of your lens just like a filter does and is activated just like a normal flash.

A quick search has come up with this page, just so you can picture what I am talking about.

:twisted: Buy an other cam!

Just kidding.... I think you should try to correct in photoshop. I donīt like to make any modification in my pictures but in this case it can be necessary.

If you want "consistency" just use your scanner - actually it works very well for coins.

When I saw this topic about the coins, I thought how It could be with my Canon A200.... Frist I tried to take picts with natural light, but the picture were withought live.

Look this:



Then, how it was not good, I tried in another way. I got a lantern and I make the efect. With this, the second pic was better then the first.

Are you adjusting the white balance on the camera when it is cloudy? Colors will vary with lighting conditions and you need the correct white balance setting for the light.
