Hi there, leading on from my last post, i have decided to buy a set of cokin filters with adapters and series filter holder. I'm about to bid for a used set on ebay, only gunna pay about twenty quid so its worth it, even if the filters are no good. However, the guy selling these filters has listed which ones are included, and even with help of google, i haven't managed to work out exactly what each of them are for! If anyone could shed any light on any of the following i would be really greatful! The terms and abreviations don't seem to match the terms used on the cokin, website! So if anyone knows a good resource for finding out which each filter does that would be even better!!! Any way here goes: 001 coef + 1/3 Yellow, 002 coef +1 orange, 028 coef + 1/3 Warm (81 C), 056 Star 8, 060 Spot- Incolor 1 160 linear pola ..........(i'm presuming this is a polariser?) 197 Sunset (graduated).........(i presume this is just something to add a sunset effect? Could do that in photoshop!) 830 Diffuser 1 .......(is this like to make the image softe???) As you can tell i need all the help i can get!!!!! So Thankyou!
