#smoothwaters will cost you only 50 cents! I always wanted to get those blurry foggy waters you get with 100s exposure time. Pros do it with those very expensive dark #neutraldensity filters (they stop a percentage of the light coming through the lens and this percentage is equal for each colour). Well, #weldinglasses are not even a 10th the quality of an ND #10stops filter.. yet not even a 100th the money! I bought the #cheapest welding glass i found for a half euro. And these are the results! It takes a while to get confident with it, but if you know #basic photography, there's a good chance you'll hit the perfect spot in the first four shots. Here's #howto #1 welding glasses are kinda green, so, analogically speaking, you should use a #bwfilm to only get an effect of lower contrast instead of fake colours (low ISO to extend the exposure time and have fine grain). #2 tripod's needed aswell (or a steady surface). #3 Remote shutter control would be a good idea too #4 and don't forget a timer! #5 set the aperture quite low (22-16-11) and read the lightmeter (EG: f/16 & 1/125s) #6 mount the welding glass on the lens (whatever way. just make sure there's no gap between the lens hood and the glass. EG: use some tape) #7 Adjust the camera (high aperture) in order to get a correct exposition (EG: f/5.6 & 2s ) #8 Now do some math and find out your glass is EG: an 11 stops glass! (mine was 13). #9 Done! You know the stops and, if you know what a #stop is, you can calculate how long you should keep the shutter open #10 I suggest to calculate the time by doubling the actual number you read on the meter EG: 1/30s - 1/16s - 1/8s - 1/4s - 1/2s - 1/1s - 2s - 4s - 8s - 16s - 32s - 64s - 128s - 256s (give it some seconds more!) Hope everything's clear. Ask any question!
