<p>[QUOTE="bruthajoe, post: 3951625, member: 108656"]I'm actually having problems with LEDs. Although they make very good light and you can get them in different temperatures. I think some LEDs operate on a frequency that tend to sync with the refresh rate on digital devices and you can get all kinds of lines. Most of my pictures are taken under an LED shop light. I notice the horizontal lines, their subtle but I notice them. PCGS recommends using incandescent bulbs between 60 and 80 Watts I think with two light sources. They say halogen is also good sometimes for picking up details. They do not mention led's. If you are able to take a slow motion video of your lights you can see the effect. There may not be a noticeable difference between incandescent and led but the LED seems to have a refresh rate or rather a frequency that interferes. IMO. Below the .GIF is an LED shop light in slow motion.[ATTACH=full]1041175[/ATTACH][/QUOTE]</p><p><br /></p>
