I wanted to try a polarized filter on the el nikkor. well its not pretty but it does work. I have a couple of shots with the polarized filter. I think they work not to bad used a piece of abs pipe and some glue and a couple of set screws. the silver dollar is near mint. and the nickel is very bright high lustre

You are doing what I'm doing, taking shots and wait for someone to tell you what to do next. The pics are dark and the dollar has good detail, the nickel looks a little burry. That's all I've got lets see what they say.

When you use the polarizer in front of the lens, are you also using one over the lights?

mcshilling yes but I find I can get the same effect with just closing down of the f stop. so polarized filter really did not do much here. pepactonius yes I was wondering what would the polarized filter do on the janjso lamps. think I will try that next to see what I get. when I get that rigged up I will share a couple pics. see what you think. think I have a fix for a micro focus adjuster . need to find a couple of pieces. once I have it together will show every body how I built it have a great one

I think I have finally understand what ray and dave has been trying to tell me. I just got done reading rmc thread again. I was taking photos last night with the canon camera. but every time I would get it just right. when I took the photo it would be way to bright. I thought I have to read rmc thread again. finally it was like a light went on. I remember what ford perfect told me and showed me with a picture. so I thought follow daves lead make all the setting in live view. heres is a pic of a half dollar from the canon and the el nikkor 75mm. finally I know how to darken the shot from live view and how to adjust shutter the f stop plus the iso. thank you guys so much and thank you rms for a great thread

Rocky, "Gonna Fly Now.."(theme from rocky). Nice shot. Lighting and post production are what I'm working on now, looks like you are there also. Taking good photos is both and art and science. I think I have 90% of the science, now its the art. Every shot requires me to constantly tweak the lights. There is no universal lighting setup.

wizzy 1 yes I see by your comments. yes you have it as well. I read the thread by rmc and ray and dave would tell him to make notes. I know understand why like you said. we will always have to do a little tweaking as we change coins. wizzy 1. I have some coins I want to move on ebay . I have found and easier way to photography them. lighting with this lens is not as difficult. I still use my same camera and same lights. the lens is so easy and cheap and it will work with all coins. there is another member that has a similar lens. I know his is a lot more expenses. onces I seen how good it worked I brought the whole set to test them and all I can say is wow. but they do not preform like the enlarger lens. they make coin photography very easy. have a great one wizzy1 keep taken them photos

hello pepactonius thought about what you said about the polarizer. so got a special glass made from a glass shop. they installed the polarizer on the glass. here what I got with the canon t1i and 75mm el nikkor . two janjso lamps at 10 and 2 and muslim clothe for diffusion on the lamps.

I was just wondering if "crossed" polarizers on the Jansjo light and the lens might reduce the shiny reflections from the coin. If this actually worked, it might allow longer exposures before the highlights burned out. Of course, there might be problems like color shifts, etc., and maybe it doesn't work at all?

It does work. I tried it a couple years ago using linear polarizers. But it gave an "odd" look to the image and I was not impressed enough to move forward with it except as an experiment. As I remember, it also resulted in extremely long exposure times since so much of the light is blocked. Maybe someone with a finer touch at these things could make good use of the technique by carefully managing the polarizing angles to get just the right amount of extinction. I don't remember a huge color shift, but keep in mind that luster and other important aspects of the "in-hand look" also get blocked. What the technique may give you is a way to use a single light by minimizing the strong highlights single lights cause, but this is only speculation.

yes I was talking with some other photographers. they looked at the images and told me to try the new low E glass. they think the polarized film is way to dark. they said low E glass is about half that dark. one showed me how he takes pictures of jewelry using axle lighting from a cfl unbelievable. that is not to hard to do try that later.

ben doing some picture taking with a few different lens el nikkor 75mm el-omegar 75mm vivitar 75mm componar 80mm. all exceptional wonderful lenses. my problem is that. I find my coins appear better than they are with these lens. so I read a other forums and finally found a lense. that when I take and image the image and the coin match. still use my canon camera the lens I brought of ebay came already attached to a bellows. the lens is Minolta auto bellows rokkor 1:4 100 mm. here is and image from that lense. I am going to sell my collection and need the images to match my coins. I find this my best match any suggestion greatly appreciated. I also tried a super takumar 50mm same out come. they are easy to work with and easy to light the coins.

What about the image from the 100mm is more realistic than the other lenses you mentioned? Are you lighting them the same, or is the 100mm giving you different lighting choices?
