My get pushed challenge this week is from JackieR and the challenge was to do a surface rainbow refraction (ie not through water) which is found in bubbles, oil, shining light through some plastic / perspex etc.
I tried doing this last night with only moderate success. According to google I need to add some drops of glycerine to strengthen the bubble so it has a chance to develop some colours. I am away from home at the moment but had a go with soap bubble mixture a glass and a straw. The bokeh effect is from lots of little bubbles. I got a wee bit of rainbow on the large bubble. Will try again some time.
@dkbarnett im so sorry I failed to do your challenge. We went on a boating holiday and I took wrong lens. I've been trying to plan gulls and ducks, failing miserably. If/when we're partnered again very happy to be give me that challenge again!!
I have managed to take one or two photos successfully!! Have to manually focus plus use the screen as a touch screen for shots. That doesn't always work either, and sometimes it is taking shots all by itself! So yes - have resorted to iPhone at times.
