The professional look is often what clients require in their advertisements and PR campaigns.
Especially for PR campaigns, frequently we find clients seeking a very professional image in the advertising photography.
Such clients can belong to different verticals - be it some educational institution, an organisation in the petrochemical industry, an airline company or a hospital.
Different clients want to show their skill and professionalism in their advertisements.
When you have such client requirements, then your advertising photography needs to be highly professional too.
Let us take the example of it for a hospital.
Your client may want to convey to the audience about 'highly qualified and skilled doctors' or the message may be 'the advanced technology used in the hospital'.
And to convey that message, your approach should be absolutely professional and closer to real life.
Every advertisement has a message to be delivered to the target audience.
And therefore it is necessary for every element in your picture to contribute to the message that the client wants to convey.
In the example of this for hospital, you might want to show the different equipments being used inside to convey the use of advanced technology.
For that you can have the backdrop of an operation theatre and give a slight blur effect to it to put the focus on the models.
Now that brings us to modelling for advertising photography.
As I had mentioned that every element should be closer to reality that essentially includes the models too.
You may have to show professional yet compassionate doctors.
For that it would be better to use bright looking models with kind faces and an average body structure.
We don't need hot models with well chiselled figures for such campaigns.
Also for the patients, it would be better to use models who look like the ordinary common man (or woman) to get as natural as possible.
