Photoshoot for Crocheting Webshop

Last week my daughter asked me to take some pictures of crocheting she makes and sells via her Etsy webshop, DC crochet Design. She was facing some shortcomings of smartphones to do product photography. So, yesterday I grabbed my equipment and turned one of our bedrooms into a small photo studio. I have done something similar before so the first steps were easy.

  • To put all the focus on the crocheting I used white paper as a background. I used the same equipment as for model shooting, only I used a more narrow roll of paper.
  • To avoid sharp shadows I used two compact flashes flashing from two different sides through white umbrellas (TTL-mode). 
  • To avoid incoming daylight I set the Exposure Time to 1/160th of a second.

This is the way it looked like.

Studio for product photography

As a camera I used my Nikon D800 and the Nikkor 28-300mm as a lens. I set the Commander Mode such that the two compact flashes on the side flashed and that the built-in flash did not.

During the shoot my daughter and I checked the pictures to make sure that things were working out the way we wanted it. Here are some of the challenges I was facing:

  • The white background is not white at all Compact flashes are of course not as powerful as studio flashes. I have only one studio flash, so I decided to use two almost identical compact flashes. In Lightroom it is very simple with the adjustment brush to increase the exposure to make sure that the white background is really white.

  • Not the whole embroidery is sharp In most of the pictures the whole crocheting had the same distance from the camera. In this case f/8 suffices. However, I did not realise that the Depth of Field was pretty small. Afterwards, I calculated that at 115 mm and with f/8 or f/10 the DoF is only a few centimeters. Too small as you can see here. The bottom of the iPhone is not sharp.

    From this I learned that I have to shoot a bit further away, with a wider angle than 115mm (for example, 50mm, and crop later), and at least f/16 or f/22 (all increase DoF).

  • Colours are not identical to original I fiddled around a bit with the  temperature to match the colours of the original.

So, next time I am better prepared.
