OK, so we are still in coronavirus lockdown here in the UK and I have spent the afternoon playing! \ud83d\ude42 I saw the basic idea on a web forum on a photography site, and decided to look around my garage and see if there was any thing suitable to produce something similar. I also took a few quick hand-held snaps of the results.<\/strong><\/p>\nngg_shortcode_0_placeholder\n

Details<\/h2>\n

This is my last piece of (rather battered) perforated stainless steel sheet, cut to a roughly rectangular 29cm x 18cm, c\/w edge protector (to prevent cutting ones hands on the sharp edges). Excuse the extra hole. It had that already, but it seems to make little difference..<\/p>\n

Above sheet of perforated stainless steel, handheld a few centimetres in front of one of the 20 watt LED spotlights I modified and discussed in an earlier post<\/a>…<\/p>\n

\"\"<\/a><\/p>\n

Transpires that due to the matrix-layout of the COB LED in the lamp, Moir\u00e9<\/a> patterning causes light to appear as lines, similar to light shining through blinds.  By holding one end a little further from the light source than the other, one can add perspective to the pattern it throws, like so…<\/p>\n

\"\"<\/a><\/p>\n

Rotate the modifier through 45\u00b0 or so, then you get this rather more jagged pattern…<\/p>\n

\"\"<\/a><\/p>\n

I have not had time to play any further. But considering this is just a piece of scrap metal, I’m rather pleased with the results so far. \ud83d\ude42<\/p>\n","protected":false},"excerpt":{"rendered":"
