Flowers shot with extremely shallow depth of field
Here’s a lovely image of some purple & pink springtime flowers.
A guest brought them to the house when she came over at Easter. This was the first time we had received guests since lockdown has been eased, here in the UK.
I’d been planning to shoot some flowers for a while…
I thought I’d dedicate this image to my Mum, Rita. She is patiently sitting in her house waiting for normal life to resume. Sin upon sin, I didn’t mark Mother’s Day with a gift this year, so this is me making the effort for me ol’ mum.
“I hope you like the flowers Mum”.

Pixel Peepers’ Notes & Newbie Hints & Tips:
Sony A7RIII / FE85mm f1.4GM – 1/[email protected] – ISO100 – cropped – (pixel array 4188×5978).
The Brief: Create an image that echoes the Impressionists and Fauvism, using only focus as a tool. Do not introduce movement to affect the image. This is overused, and a commonly used shortcut. We’ve all seen the dancer with movement. Do not use Photoshop to change the image. Use simply depth of field and focus to create an impressionistic image of flowers.
Lighting Set Up: This is shot using the only natural sunlight. I did not use any reflectors or lights. What you see is what the cosmos provided on the day. The sun is out, but it was being diffused by light clouds. This happened to be ideal for what I was trying to achieve.
Retouching: This shot has been graded in Adobe Camera RAW and minimally retouched in Photoshop; I have taken out a few marks on the foliage only. I did not retouch the flowers.
Newbie Note: In terms of composition, there’s no trick to shots like this. I placed the flowers into a neutral coloured vase, and placed them on the patio in the studio garden. I bent over them with the camera and focussed on the flower on the top. I did not arrange the flowers in any way, (I would have if they didn’t look good!) and I composed the shot by moving in a out and rotating around them until the composition presented itself.
Depth of Field: This image required the shallowest focus that I could achieve. To achieve this, I shot the Image using the minimum focal distance from the subject. I opened the lens to the widest aperture. I chose the longest lens that would allow me to practically stand above the flowers and fill the frame:
Sensor Size: 36×24
Metric Lens to Subject Distance (Stamen, top flower): 80cm (800mm)
Imperial Lens to Subject Imperial (Stamen, top flower): 31 1/2in
Metric Result: This gives me a metric depth of field of 0.67cm (6.7mm)
Imperial Result: This gives me an imperial depth of field of 17⁄64in
In effect. I actually didn’t want anything to be in focus, but that would cause too many problems for most viewers of the work. Even I have to subscribe to at least some part of the image being in focus. Note that I am not talking about movement here… It would be easy to simply add movement to the image to create a more impressionistic image.
The image is after Impressionism, and indeed, after Fauvism too.

In a world that has experienced the hyper-real HDR craze and now hyper-sharp images, it can be difficult to achieve an image that has an acceptable subtlety, without being pin sharp.
I have screen grabbed the image so you can see the sharp detail on the file:
Overall I am happy with the image, although I would prefer it if the focus fell away quicker, but for that I would need a wider aperture, as I was at the minimum focal distance from the image. If I used the next, longer lens up available to me, I would be on the Sony FE70-200 2.8GM, and whilst that will give a shallow depth of field too, it only opens up to f2.8. The minimum focal distance would have had me on a ladder as it is 96cm, according to the Sony website, but it would halve the depth of field @0.31cm.
I think I’ll shoot some more images of flowers soon.
I hope this information is useful to some people starting out – Colin
