If you need to take some fancy-looking photos of your items with a smartphone, you can use your computer monitor for a bright background and set your item on a flat, reflective surface.
YouTuber Dylan Hart -- AKA the HouseholdHacker -- demonstrates how you can get that professional photo look in just a few steps:
- Find a bright, full-screen image for your background monitor (he recommends using "bokeh" images).
- Find a shiny, somewhat reflective surface and set it so it's flush with the computer screen.
- Set your item on the reflective surface and shoot away.
You can add lighting if you need it, but now you should be able to get some professional-looking pics of your item. Taking decent smartphone photos isn't always easy, but there are lots of ways to get the best out of your smartphone's camera.
