These are pet portraits taken with a 85mm F1.8 Sony Lens on an A7 ILCE full-frame Sony camera. No flash or lighting equipment was allowed during this particular dog show but the overhead lights (ambient lighting) were more than enough for a fast lens. All photos were set to F1.8 for maximum background blur.
Using natural light (also known as ambient light) means no flash or special camera lighting was used.
Natural lighting from the sun is what was used for the photos below. The next time you are out taking photos in the daytime, try taking your photos in the shade for a softer look.
