Although the trend is the disappearance of the style, I think that the personal architect brand is something that should be continually claimed. Your proposal is part of you and that is to be shown.
If you have not found your own style you have to investigate, do tests, find out. It is a task that can take years and, in many cases, is not achieved.
But please do not resort to outdated stereotypes. People are tired of seeing images of buildings with pictures of people out of scale in black and white.
Your images are like your wearing style. If you want you can make all your clothes to be black and go out with interesting face thinking “people realize I’m an architect”. If you want to you can present these images and get comfortable in front of other colleagues because you believe you are cool.
But, sorry, you’re not.
Apart from those looking for that style, there are those who, due to technical limitations, they cannot choose another. I do this because it seems outstanding and I don’t know do to anything better.
To get out of this situation there are two ways:
Learn or hire someone who knows.
Both options are valid. Good visualization companies capture what you want and know how to do it.
As you secure this collaborative relationship, everything will be more agile and your imagination will be broken free.
Learning requires more time and resources. You will just know which fits your situation better. In addition, this style can be variable depending on the competition and even on the composition of the jury.
