4. Quick hack
For flowers that grow close to the ground, a small support can make photography much easier. One simple solution is to create a makeshift mini tripod. I often fill a travel compression cube with beanbag beads, which creates a waterproof and stable base to rest the camera on. It’s particularly helpful if your camera has a flip-out screen. An even simpler option is filling a large freezer bag with dry rice or pulses, which can be shaped into a steady support and will balance a smartphone quite easily.
If you are familiar with adjusting apertures (the f-stop), remember that both lenses and phones have a minimum focusing distance. Macro lenses are often used by photographers who want very close-up detail, and they are available both for DSLR cameras and as attachments for smartphones. Because macro lenses focus so closely, depth of field becomes extremely shallow.
When using a small f-stop number such as f/2.8, only a very small area of the subject will appear sharp - even more so when you are working very close to the flower. For maximising detail, starting around f/5 is often a good approach, and you can adjust from there depending on the effect you prefer. If your phone’s portrait mode allows you to adjust the f-number, it is worth experimenting with this as well.
