MontCollector thank you that was a very good read. I like how this person walks you through. the test that was done. I have been doing a lot of experimenting with lights camera lens. I have been thinking a lot lately about taking my whole setup apart. build a mount shooting every thing vertically. buying a big macro lens something that moves the camera back 2 to 3 feet. just to see what I get. this would allow me to change the angle of the lights. I want to get rid of lens reflections. I found a light on ebay. I purchased one. they are made in Germany. the light has a special grooved disk. the light in the center is the same as the edge. you can shoot through the center of the light. I am hoping this eliminates the lens shadow. if not I take every thing apart and start over.

Your welcome rocky. Glad it helped.
I have 2 florescent lights both in gooseneck desk lamps and just bought a halogen spotlight for another gooseneck desk lamp. Have lots of desk lamps so total cost was for the halogen bulb. Found at my "local" (50 mile round trip) hardware store for $9.99.

Make sure that the lights (which are now off to one side of the coin) are very even and diffuse, so the reflection off the coin is uniform. I had to do this once to bring out some date details on a slabbed coin. The glare off the slab needed to be very uniform, so it could be subtracted out in Photoshop to recover the coin image, with acceptable contrast. The result was not ideal, but al least you could see the date.

MontCollector thank you. I find that with coins depending on the metal. there no one way to light coins. I am going to try this light out of Germany. if it works. I keep my same setup. if not take it apart and make some changes. when you get a chance. I would like to see some of your photos have a great one.

pepactonius that sounds like some thing. I may need to try. pepactonius this new light may help. it has a special diffuser. plus the light is dispersed evenly across a cross a 9 inch plate. the plate has special micro grooves. that keeps the light even plus the light spreads out like a cone. at maximum it is 6500k daylight. it is designed to be dimmed. to light what ever metal evenly. with out reflection. plus there should be no reflection from the lens on my camera. you shoot through the center of this light. but I have purchased stuff before. I find it don't do what they say it will do. I will find out soon. I like your idea. I know you do good work with coins. thanks for the suggestion

here is a pic of my cheesy set-up. I don't have a lot of money and I bought most of my Camera equipment for taking awesome shots of wildlife here in Montana...shoot I can take a pic of an animal at 300 yards and make it look like I'm right next to it. But when it comes to indoor macro shooting I am LOST. Sorry bout caps.  Pretty Cheapo but it does allow me to change up mu lighting angles. Should I put something white on the table to reflect light back up? Also how far should the light be from coins?

I like your setup. we all like to use what ever works. ok first what is your camera. what do you have for lens. if you don't have a macros lens. there is other ways to over come that as well. I can tell you. there is a lot of members here more than willing. to help you same as myself. so camera plus lens first. then go from there

Woohoo!! I just found a piece of plexiglass perfect size!! Now I got a diffuser!! Upgrade time. LOL I have a canon Rebel T3 with 2 macro lenses. The one I use is the 18-55mm that came with camera. The other one is a 55-250mm but that one has a min focus of 1.1m/3.6ft. The rest of my lenses are serious telephoto lenses. I also use the software that came with camera for live shooting mode. I don't have a billows or a tube extender. Do I really need these? Can take descent pics of whole coin...but can't zoom in on any particular part and take pic. Is this a lens or software problem? Would love to zoom right in and snap pic to be able to get some of my Morgan dollars VAMed.

If you want to take closeups (for example at 2x, 4x, 10x magnification) You'll probably need special macro equipment of some sort: - Closeup lenses that fit into the lens filter threads - Extension tubes or bellows with special lenses that do well at larger extensions - like bellows lenses or enlarger lenses, or even low-power microscope objectives. - Teleconverters that can also work to increase magnification in come cases. - Macro coupler, so that you can use one short focal length lens (reversed) on front of a longer focal length lens (like a short telephoto) -- I suppose this setup is somewhat like a closeup lens. I wonder if your super-telephotos for wildlife might work as the main lens in this type of setup?

The only tele-converter I have is a high def 2.2x telephoto converter that screws onto any lens/filter. will that work for close ups? When I zoom in with it, it looks like I am shooting down a tube.

took sever pics of same coin in different lighting.  The one above is with all light on  with both OTT light on  with one OTT light behind a leaning piece of plexi-glass acting as diffuser. Which one looks better to you?

When I zoom in with it, it looks like I am shooting down a tube. I was referring to the type of teleconverter that fits between the lens and the camera. These magnify the central part of the image from the lens before the camera sees it. In order for this to work, the lens by itself needs to have some sort of close-focusing capability. For example, if the most your lens can do is 0.1x, a 2x teleconverter would increase that to just 0.2x, maybe good enough for a 5-oz coin.

I ordered an autofocus tube extender kit should be here next week. Comes with a 13,21, and31mm tubes. Cant wait to try them out. If I understand correctly, these will decrease the minimum focus range for lenses. Should I use my 18-55mm macro lens with this kit or will it decrease it enough for me to use my 55-200mm(1.1m/3.2ft min focus) macro lens?
