OOoopss.. I forgot to feed in about portfolio, didn't I? My bad!
2. OK, portfolio in simpler language is a collection of your photos. Portfolio is much preferably professionally taken photos such as taken in a studio or taken by professional photographers: either in the studio or outdoor. Usually photographers are brilliant in adjusting the lightings, so even when you are taking photos outdoor, the outcomes will be the same with the photos taken in the studio. In conclusion, your portfolio should be good quality photos, NOT TAKEN BY YOURSELF BY CAMERA PHONE!
3. Usually portfolio only needed minimum 3 photos:
a. Face close-up
b. Mug shot (Half body)
c. Full body
**** If you dont have any contacts to do studio photos, don't hesitate to leave a message or comment. I will try to find photographers or perhaps a studio for you.
