As in 2016, this is part of my contribution to 2017's P52 challenge, in the form of a series of odd threads from the Photo shoots I do with my grand-daughter Chloe, just they happen less regularly (but take more effort).
The brief for this shoot was Cake Smash, which seems to be popular on social media.
We (Chloe's Mum, Rebecca) and I did our research and the plan was a white background ("bg" hereafter) and some bg decoration, but not so bold as to compete with the subject, also; I'd use aperture/DoF and shooting/bg distances to keep the bg in fairly soft focus. I hope you'll agree this part of the plan worked well.
For the bg, I currently only have the sheet variety and these are notoriously prone to show creases, I think a seamless paper roll is going to be a necessary addition to my kit soon. Problem is; they seem to come in two widths; 5 ft (too narrow) and 11 ft. (too wide for our rooms), so I may have to get an 11 foot and cut it down a foot or two, but I digress...
Research suggested that an acrylic sheet under the cake would be a good idea and fortunately I managed to obtain one from a local hardware store, it measures 1.2m, or 4 feet, square. There are bg 'ripple creases' visible through the acrylic, but hopefully not enough to distract too much, I didn't even attempt to reduce these in PP.
Light was provided by 3 speedlights set on Manual, so I set and left camera settings also on Manual as follows: shutter speed 1/200 (below sync speed, so no HSS necessary), aperture f/4, for (hopefully) adequate, but not excessive, DoF using the Nikon 35mm, f1.8 lens on my D7100. ISO was 200 (base).
Flash powers were all controlled from the Godox X1T-N RF trigger on hotshoe for the three groups in use; A=main, B=fill and C=bg backlit.
The main and fill were Godox TT685N (built-in) RF triggered (gotta love this system!). The main was aimed in to a 36" white reflective umbrella, the fill was shot through a white 26" shoot-through umbrella. The flip down '14mm' WA diffuser and umbrella shaft distances were adjusted for good coverage of light in to umbrellas.
The bg was backlit by my single remaining flash, a Godox TT600, also RF controlled and triggered. After the first few shots, a large diffuser had to be introduced between the flash and the bg to soften the hotspot and its acrylic reflection. I was constrained by not much space behind the bg to increase distance and improve light spread.
Flash power was balanced by chimping for a good result, the majority of shots being with powers set as follows; A: 1/6, B: 1/25, C: 1/32. Interesting how much loss the reflective (main, camera left) had over the shoot through (fill, camera right), requiring much more power, they were at similar distances of say 1.2m or 4 feet at 45/45 to the cake. That said, I'm not sure I didn't over do the main flash power: Question; do the skin tones look a bit washed out from 4 onwards?
The weekend that Chloe and family came to stay with us for the shoot marked her transition from crawling to walking as her 'default mode' of movement, which caused a few issues for me shooting with a prime lens; one minute she's sitting down, the next moment, she was up and off

I used PS CC to process the images.
Due to the controlled conditions (and good exposures), I found I rarely needed to change much in ACR, histograms looked good SOOC. What I did was mainly to reduce crease visibility.
My camera's "Flash" WB setting seems to be 6300, -2, so I changed them all to a more standard 5500, +2 which looks better and matches eye dropper samples. This is something I won't bother to use in future, I should be shooting a WB reference and using that, I have a Whi-Bal card, just gotta remember to use it
What caused issues was removing the 'joins' between acrylic and bg sheet*, plus especially the creases in the latter, fortunately; the Content Aware Spot Healing tool proved quite good at this, but it still took time.
* I'd managed to light them to a reasonably similar brightness, which helped a lot.
Other lessons learnt (not mentioned above):
- I paid attention to focus as I'd had to cull far too many frames from the Xmas shoot due to 'missing the eye', in general, this shoot was much better, with far less culled due to bad focus.
- Framing failed several times due to the subject suddenly advancing beyond my ability to scoot backwards quickly enough to avoid clipping toes, hat/head, or both - I'm thinking a fast, constant aperture zoom would be nice, but I'd possibly have been able to maintain aperture at f/4 even if I'd used the 18-200mm (f/3.5-f/5.6) between say 25 and 35mm, but that might have changed aperture, hence exposure, but then again, moving forward out of the 'light pool' did that anyway!
- BG illumination wasn't even at transition from horiz to vertical, but I couldn't front light it as I only had one spare flash, so that had to be centrally placed behind. This restriction has since been remedied by buying another TT600
- I did need to do a lot of levelling of the shots, the reflected points of the bunting proved useful aid for this, often this led to needing to 'clone fill' some empty corners.
- I think I might have achieved a slightly better balance of lights by reducing the main a tad, say 1/8 or 1/10 from 1/6 and increasing the bg backlight power a bit too. The aim be to maintain a constant white bg, but reduce skin tone exposure somewhat.
Unlike the Xmas shoot, there was no single standout image this time, which left me (at least) feeling a bit deflated. I've seen worse (and better) results shot by professional togs, but for a 'first time' effort, not too bad I suppose. Perhaps next year she'll be more in to smashing the cake, I think it was all a bit of an unknown experience for her. Mind you, training her to 'play with food' could have unwanted repercussions - just as well it wasn't done in her high chair, as some are shot.
The cake survived quite well I thought
(it was soft icing too)
