I used to use glycerin diluted in a spray bottle. I wonder if using a linear polariser would give rainbow colours in the plastic LED like it does on CD cases. Polariser daft am I.
I've got a cheap linear polariser on order to try out. Also tried the 50D's response to an IR LED, which showed, so also have a cheap 720nm IR filter on order to play with. Ummm - thought - rainbow colours should be possible from CD/DVD surfaces.
Not the CD/DVD it's the case they come in. Any clear injection moulded plastic does it. All round the corners and such places where stress was introduced whilst it cooled. In case you have never noticed if you want a circular polariser set up to optimum look through the camera at your lap top screen and it goes black at full chat.
I look forward to seeing the results of the IR filter. Not a medium that has ever grabbed my attention. Be good in the dark but for that I think the camera has to go away and be destroyed...altered I meant.
Adrian yes - a CD gives rainbows without filtering - interference patterns? The IR may not work. Has to use live view for focussing, if anything can be seen, and takes long exposures from what I have read today. The 720nm type is at the gentler end of IR filtering. Worth a tenner or thereabouts to get it out of my system! As I have two 350D bodies I have occasionally thought about having one of those 'altered', or maybe the Fuji I never use these days.
Thank you for visiting. Hope you enjoyed the pictures. Any comment, or correction to any information or identification I get wrong, is most welcome. John
These are cracking shots.....I've never managed to get an image through a rain drop.
ReplyDeleteI failed miserably with some rain drops yesterday Adrian. The sap, being thicker, has worked well in the past.

great shots!! really love the droplets!!
ReplyDeleteThank you TWG. I've tried the sap droplets in the past and had reasonable results.
DeleteGreat shots John, especially the second one.
ReplyDeleteThank you Roy.
