What’s The Best Shade Number For Welding Glass Attached To A Webcam Which Is Used To Record Images Of The Sun?
Hi, I am trying to use a webcam (Logitech Quickcam Express) to take pictures of the Sun throughout the day for one of the projects I am working on. In order to protect the camera lens from being burnt by the direct sunlight, I think it might be a good idea to place a piece of welding glass in front of the camera. However, I need to determine the optimal shade number of the welding glass for my particular application. Does anyone know what shade number(s) I should choose? Thanks.

How Do You Pick The Correct Welding Shade For Different Types Of Welding?
For MIG and Flux core welding, do you need a differently rated shade. We have a # 10, and don’t know how to tell when we could need a darker shade like a 12 for example. Somewhere we read about looking at a bare light bulb to see if you can see the outline of it as an indicator of needing a darker shade. We are just learning about welding and would like to know when an auto darkening system is better and how to pick a good one.
thanks
