Hi all firstly this isn’t a guide to taking general pictures, cropping, uploading etc, there are some great threads already on the forum for that. However you may be able to utilize some of this for your set up. This was requested by “Danish John” as he has just ordered a new camera, what you will need, SLR camera, approx 50mm lens, x10 magnifier lens, lighting ring, Paint shop Pro 5. Set the camera level on a tripod and use a spirit level to check, in front of a window, not direct sunlight as this is too harsh. Mount a piece of glass or Perspex with a couple of inches of gap between the camera and a white sheet of paper, this stops shadows. Use “Manual “everything on the camera settings, and fit the x10 magnifying lens, if you haven’t got one you will have to focus from much further away. PS I sent you the link for the cheap magnifiers on Facebook, lighting ring also from same auction site, think that was about Ł40, anyone needs details of these bits PM me.
Picture one shows the un-altered picture, aim for an exposure time of 1/100 sec, but with a tripod you can go lower, I also have a remote control to take the picture so can go much lower with no camera shake.
Picture two shows the picture after a “Flood Fill” with white and “Brightness & Contrast “ adjustments, this will give your picture more definition and look less flat, the values will depend on the brightness variations of the daylight on the day.
Picture three shows after the image has been “Gray Scaled”, you may think why on this coin ? but on some poor quality Silver coins that are very patchy it can improve the look of it, also I found after some time my collection on the web looked all different because of the varying lighting conditions, this uniformed all the images, on Silver artifacts I go one step future after this to alter the ”Gama Correction” and add a tiny bit of yellow back to the image to make it resemble the original item.
Picture four is the cropped to shape and re sized to 300 pixels which is what I use on my web site, a little tip on all “*.JPG” images is they need not be lossy, when saving adjust the options, normal compression quality is 15%, I use 5% for mine but if you set at 1% it is really good, but off course file size is larger.
Ok the problem here is depth of the item, if you used the above set up you will not get it in focus, although you can photo stack by taking more than one image at different focus and then use the draw program to cut them all together, I have done this but it is complicated. So take the x10 adaptor off and adjust the lens out to make a smaller image, this improves the focal range as picture five.
Now second problem is a dark side and a bright side, in conjunction with the light I use a LED lighting ring on the camera as picture six. PS Don’t use the lighting ring on flat items like coins as it will knock all the depth out of the item and make them look very dull and boring.
Repeat the same “Brightness & Contrast” adjustment and crop and you get picture seven.
Hope this all makes sense John, by the way Paint Shop Pro 5 is all I use, it is old and cheap to buy, but all what I have done can be achieved in most draw programs, any questions let me know. Dave
