I expressed the model's cuteness and youth.

The model has a distinctive eye shape.

The model stood halfway up the stairs and I photographed her from above.

Her eyes widened.

It's the season of fresh greenery.

The sun is above our heads and backlit.

Therefore, the model's face became dark and her white blouse became green.

I fixed the photo with retouching.

My face is dark so I brightened it up. The sunlight reflects off her shoulders, illuminating her face from below. I especially brightened the lower part of the face. I fixed the green overlay. I especially paid attention to her white blouse. I adjusted the leaves in the background to bright green instead of dark green. The bright green emphasizes the youth of the leaves. I had the most trouble with her face and the color of her blouse. In my first post, someone pointed out that the background was too bright. In the second post, I made the background darker. But it's not good. Please let me know where I should improve.

Hi Kazuaki,

I like your photo very much and although I am not a portrait expert, I would like to offer you my editing suggestion: I have turned the photo 5 degrees to the right so that the stairs are straight - in my opinion, this increases the effect of the very pretty lady on the viewer. I also increased the sharpness slightly - which is a matter of personal taste - but please see for yourself:

Greetings

Dear Kazuaki,

It's dead-simple, never put a model in bright sunlight. You have over-exposed areas on her hand, shoulders, on the top of her head, in some areas of her hair. Contrasts of a mid-day sun vs. a shadow place are simply too high to capture it in a dynamic range today's cameras cover (11-15 EV). 

The position you chose is not too bad if I'm not mistaking, because I think you got reflecting light from the concrete of the stairs. If you find a place you have that indirect light coming off a wall or ground and put your model in shadow, that's the "magic" light you need for a environmental portrait. I think I mentioned it a few times, I shoot weddings. So the time and weather is a given, I have to live with this harsh light and still have to deliver. So that's what I'm  looking for. If I can't find it somewhere because for example the couple wants to  shoot in nature, I ask somebody to assist and bounce light off a white or silver, 7 foot reflector. Silver is difficult in very bright sun, there white is better, pretty close to the subject, though.

The alternative to balance environmental, bright backround and a person in shadow is outdoor studio flashes and using 1-3 stop ND filters to keep the aperture open. But that's complicated, and the model may get annoyed by the time it takes to find your settings. If you booked a pro model, she may not care. But otherwise you potentially don't get what you want and I like in this shot, a very genuine smile. Mark Wallace is a good teacher when it comes to handling light a simple way. And though I don't like what he achieved here with a frontal light, it gives an idea of how to balance light with flash: https://www.youtube.com/watch?v=Y_sGYkT42Bk

Talking about your model, she's a pretty lady, but the posing of her hands tells me she did not know what to do. They don't make sense at all and it gives the photo an amateurish attitude.

Best regards,

Mike

Thank you very much for your very valuable advice.

I have a monoblock strobe (AD300) and a variable ND filter.

I will use it more actively in the future.

Hello Kaz,

That's perfect, because the ADx00 Series support HSS. Ouside the limitation to 1/160-1/250 exposure can be a challenge if you want to shoot open aperture, which you then counter with an ND filter. But using HSS, a 1-stop to 3 stop ND may bring you down to a range in exposure where adding a flash is then simple(r). Have fun trying!

Best regards,

Mike
