All good suggestions, thank you! I don't recall shooting at the extremes of the aperture, I think most of this was at f8. The lighting was in various angles throughout, you can tell the ones off to the side as some of the bubbles leave shadows, which I actually don't like as I prefer the shots that look "flat" like a single layer than the ones that you can easily tell the bubbles are floating on a second layer of oil. Having the lighting any lower wouldn't help much anyway as there's not much surface relief to pick up on once it's all mixing together. The slight yellow hint to the oil was something I was conscious of too however for a first attempt at the subject, I didn't mind it too much. I do think a lot of improvement could be made by anyone familiar with colour grading in video. It's not something I have much experience with and so there was very little adjustment made to the contrast or colours in post-processing.

Yep, its totally down your personal preference which colours you use. I did try to match a few colours together, I agree that the pink and black work really well, I liked the orange too. You are right about the solution getting muddy very quickly with lots of different colours, but it's fun to try and you will have to change out the milk sooner or later anyway. Personally i think just a couple is enough.

Thanks!

There is so much to do with it, you can get so many shots and it's really fun to put them all together to some music.

@@Adaptalux yes! I've actually just started doing this, just created my channel a few weeks ago. I love adding the music!

Glad you gave the video a watch anyway, it's definitely and interesting subject to try out... messy though.

When I said 'dubious', I meant to say sceptical. 😂 I used the wrong word!

Totally! I did find that it was hard to get the same vibrancy from coloured milk though so prefer using it as a white canvas to add other things. The black paint also worked really well as a "backdrop" colour, but when mixed with the milk it goes a strange grey colour. Maybe just more paint is needed!

There's not much of a process, my local recycling center has a liquid waste disposal for oil products. You're right though, oil can clog your drains if you pour it down the sink.

Thanks! It's a Novoflex, not sure of the exact model though.

I didn't try backlighting it. I would imagine you would need a very small amount of milk to make sure the light passes through, but it would be interesting to try for sure!

The glitter was worse actually, try this one and skip the glitter and she will be fine... just don't get paint and milk on the carpet!

You can use all kinds of lighting for something like this. Continuous light would be needed for video, but you can use flash too. You will need to be careful to keep reflections off the surface of the liquids though so placement of your light is important.
