Just bought a "Sade 10" filter - Anyone have a problem with soft images?

Here are two 100% crops - no sharping applied

Another thought that crossed my mind is that Image Stabilization has to be turned OFF.
Not sure if that applies or not, just thinking out loud.

It has to be the glass in some way. I have it attached with rubber bands so maybe is slipping slightly.

If you check out my flickr or website (see sig) you'll see that I'm no stranger to long exposures

I got out again for a little while this morning.
Eventually the rain drove me to seek shelter and terminated my welding glass photography for the day.

Thanks Tim, the waterfall I was hoping to photograph was upstream.
I guess this gives me a reason to go back.
I must admit I am quite fortunate to have hundreds of waterfalls less than a hundred miles from home, many a short drive from my house.

I want to try this... and deffinately cheaper then buying photography ND filters....

Anyone have any suggestion on BRANDS of welding glass that works better than other's, or is it all just trial and error? I've got 2 local welding suppliers that i deal with for work, and a few local home hardware stores, so plenty places to buy from, and obviously the internet.

Mine is cheap from Lowes. (apx. 5 dollars)
Make sure you get glass and Shade #10 is a great starting point.

Finally got round to adapting the Cokin P filter holder to take the welding glass

Take cheapo Cokin holder from ebay, and cut off both wings and the small protruding knobs top and bottom, cut carefully and try to get the surface a flat as possible

WARNING - be careful with any sharp knives
Maybe get an adult to help :rolleyes:

I didnt have any silicon to hand, but did have this left over from a small building project
IMAGE: http://www.pbase.com/jabtas/image/138316641/original.jpg
This stuff is supposed to stick anything to anything, but I wasnt too sure about the smooth glass surface
I decided to key it in a little with some sandpaper

First I covered the glass with masking take, placed the holder on and draw a template to find the extent of the clear viewing area
IMAGE: http://www.pbase.com/jabtas/image/138316644/original.jpg

Then with a sharp knife (mind fingers;) ), cut around the pen mark and roughen up the glass outside of this area, a good coating of the glue and press the holder firmly in place

Its currently drying with a heavy object on top to hold it flat
All being well its should just be a case of obtaining a few different adapter rings and the filter should be able to fit onto all of my lenses

When its dry, I shall post a few more pics of it in use
:D

regarding the WB too as i see it mentioned looking back over the past few pages i find setting it to Tungsten in camera gives a pretty good result - not always perfect straight from camera, but fairly close.

Yah, that would suck. I don't understand sanding just the glass. I could see sanding the glass and the holder. Some groves could mesh together and lock tighter together. But just the glass... I think you rubbed away some areas for the adapter to stick to...

What do I know? It'll probably work poifect! :D

Shampoo sounds like an unfortunate name for a hair product.
You're a ghost driving a meat-coated skeleton made from stardust, riding a rock, hurtling through space. Fear Nothing!
