Devil's Food?

I wanted to combine practising with water drop reflections and the Mono Monday theme of groceries; there's always a way if you think hard enough! So I arranged my drips and popped a packet of cake mix underneath. I used a narrow aperture to keep the grocery item evident. I also found that wiping the glass with Rain X helps the drop to stay round.

I keep a couple of quickmix packets handy in case we need something when the grandchild visit and we do some cooking. Even so, we usually end up weighing everything out - keeps them occupied for longer, good practice for them and they enjoy it.

I'm thinking of getting a full-frame camera - the new Nikon D750 - any opinions/advice welcome.
