Photographs taken by Mizan Ahmed, www.envythis.co.uk
Why is an author's image so important? It is significant for those who are curious about the person behind a piece of written work. But it is not ANY image that portrays the essence of an author. On the contrary, the image must look professional, natural and display a sort of 'author etiquette.'
I think Mizan Ahmed did a great job capturing my personality in these images. He gave as much attention to my candid/posed behaviour as he did to my book and signature. Therefore, an author's image is not limited to his/her attire or makeup, or even whether or not the picture is gray-scale or in-colour; it takes a great photographer to shoot a great image.
As a public figure, the author can use images for interviews, fan pages (ie. Facebook/Twitter) and personal website. It is for those readers, out there, who are curious to know the essence of an author, if unable to know him/her personally. The best advice I can give to any aspiring author who is ready for an image... 'Be yourself.'
