Hi Nicole,
Congratulations!
In layback café it is not terrible if you don't give technical details since that is after all a relaxed kick back place. Here, however, folks are going to have to put your image into PS or some other software to learn what equipment and settings you chose. So, it's a great idea to provide details so others can try out your technic if they want or just understand better your approach. Experienced photographers may not need this.
Your first picture is rather rough in composition. May I call it a snap shot? If this was the one opportunity to capture an image of a famous person and this was a photojournalist's dream scoop, a "money shot" then it would certainly be not only valuable but praiseworthy. However as a portrait, does the b.g. add anything to the image of your fiancée himself? Now, if that b.g. does indeed reflect some of the style, characteristic of his life, then maybe, it's perfect as is.
That's why pictures are best introduced with a contextual setting. What was the occaision of the first shot?
Now the second image is remarkable in how it is different! He is lit with some care. This picture shows some intent and vision on your post. Was this window light? What was the b.g.? Did you use reflectors etc and what gear did you have for this?
I must say I really enjoy these 2 pictures as they are so personal and special. The last picture seems to show a thoughtful and considerate person.
Again best wishes to you both......and one more thing, Nicole, what's the lucky man's name?
Asher
