  • Sand filters are used for water purification. There are three main types; # rapid (gravity) sand filters # upflow sand filters # slow sand filters
  • A filter used in water purification and consisting of layers of sand arranged with coarseness of texture increasing downward
  • (sand filters) Devices that remove some suspended solids from sewage. Air and bacteria decompose additional wastes filtering through the sand so that cleaner water drains from the bed.
  • The oldest and most basic filtration process, which generally uses two grades of sand (coarse and fine) for turbidity removal or as a first stage roughing filter or pre-filter in more complex processing systems.

Canon 5d mkII 24mm TS-E II f/11 69 seconds ISO 50 Lee Filters 0.9 GND (soft edge) & Heliopan Polriser i've just printed this and two other shots from the same location, also in square format and framed them to put on the wall in our bedroom. this image looks fantastic in print, the tonality just doesn't come across on screen - very happy with this and the others too. there are some purple lupins (i think?!!) on the right hand cliff in the foreground here and also a small collection of pink flowers (not sea pinks though...) that really give the image a nice balance and flow. the greens aren't anywhere near this bright either, a shame they are a little distracting on the monitor. anyway, the photo; it was taken last summer down in Cornwall, a showery morning which didn't look promising as i left St Ives but went along anyway, the plan was to get down on the beach and look for different angles down there but two things changed that. firstly the tide was higher than predicted so access was through water which i didn't fancy and although the sunrise was at least half hour away, a gap in the clouds to the north west suddenly allowed these rain clouds to start catching some colour. i descended the cliff to get a lower viewpoint than i'd tried or seen before and composed a wider view than this of the scene - a 24-70mm might actually have been of use this day but i still refuse to buy one. the cloud you can see over Logan Rock, all the way back to behind where i was stood simply glowed pink for a good ten minutes - it was immense! you can even see a slight glint of it reflected in the sand on the beach, the water too obviously caught it as well. i'll post the exif and some thumbnails of the other two images later today, got some DIY to crack on with :-( have a great weekend!!
diy pinhole
diy pinhole
Took the time this weekend to craft a homemade body-cap pinhole lens. Materials Used: 1.) Body Cap 2.) Cheap 52mm filter 3.) Pepsi Can 4.) Poster Putty/Blu-tack 5.) Sticky tape Tools used: 1.) Drill 2.) Pin 3.) scissors 4.) Dremmel Steps: 1.) Drill a hole through the center of the body cap. 2.) Cut a section of the pepsi can small enough to fit inside the diameter of the body cap 3.) push a pin into the middle of your pepsi can section - not hard enough to go through, but enough to make a dimple on the other side. 4.) Sand/Grind on the other side/dimple until you can see a small hole - best to check by holding up to the light. 5.) tape the pepsi can with pinhole over the hole drilled in the body cap - keep the pinhole in the center of the drilled hole. 6.) to stop the camera sucking dust through the pinhole - and it will - line the edges of the body cap with the poster-putty and stick a cheap UV or Skylight filter on it. Depending on how much of the materials you already had - you will now have a free to approx $12 pinhole lens to play with :) While everything will have a pleasant soft-focus - you'll find you have an infinite depth of field - basically anything from the pinhole to infinity will be 'in focus'
