Thank you very much for your comment. Yes, this is my new technique and I follow this when I see background look blank grayish or less attractive. In such case background definitely will be bit overexposed but subject not. I can change background anytime but I have been busy to explore this new technique.
Using High Key technique, although here it's very difficult to get white background and white subject 🙄.
Keep shooting 🙂 and have a nice weekend,
