Yes, ring lights are great for newborn photography as they are super easy to use and can work with any camera including a smartphone
Can I do newborn photography at my house?
Yes, you can do lots of newborn photography in your home. One of the benefits is you will already have lots of gifts and outfits from family and friends so will have an unlimited amount of props to use!
What lighting equipment is best for my smartphone?
You can use any continuous lighting in our store, but it depends on your budget. If you are wanting something less expensive then our ring lights are great for quick and easy solutions. More powerful continuous lighting is fine for older babies, but can be too bright for newborns.
Do I need a lot of power in my lighting?
You can use both natural lighting when shooting at home and fill this with a little bit of continuous lighting to help create a natural lighting effect. You don’t need powerful lighting but if it’s very bright outdoors it can help to pull the curtains.
What is the best ring light for Newborn photography on a budget?
We have our own 10-inch ring light which is perfect for newborn photography and smartphones. These also come with small stands which are great as normally you want your newborn to be close to the floor for safety reasons.
How many lights do I need?
