Save image name as input from user

I'm capturing image through webcam, I want to save the image name as input from user

   prompt = {'Enter Name:'};
   dlg_title = 'Input';
   num_lines = 1;
   answer = inputdlg(prompt,dlg_title,num_lines);

   vid = videoinput('winvideo',1);
   imagename = 'C:\Program Files\MATLAB\R2013a\bin\test.tif'; 
   img=getsnapshot(vid);
   imwrite(img, imagename);

How to name it as input from user in '.tif' format?

imagename = [answer '.tif']

if you just want to append .tif.

Personally I would use uiputfile though rather than write my own inputdlg. Then you can specify .tif via the filterspec argument.
