I think they are.  I generally do 2 professional shoots each year and then top up
With a few selfies - holiday ones in between. I'm on holiday at the moment and have taken some nice photos of myself on the beach - although bloody Hurricane Irma means I'm being evacuated today 😂 

I just did a photo shoot in August.  I  haven't put up the photos yet as it m on holiday but I will start putting a few up when I get back I will probably do another shoot in March next year
Mine cost me ?450 for 4 hrs amazing location 6 changes and 10 photos and extra images are ?20 I bought a further 8 so ?650 in total
But I did a 1.5 day tour in London and more then covered the cost of the photos hotel and a profit for myself so definitely worth it for me
But overall clear well shot photos regardless of if they are professional or selfies are a must I think in this business

I put mine on twitter and I do get work from twitter -  on holiday I've been tweeting my beach selfies pictures 

100% I definitely notice an increase in client interest once I get new photos done. A worthwhile investment 

So have I after clagging a handful of new photos up on AW earlier and I haven't even put them on my site yet. The key word is 'new' - my friend and I took in turns to do each others with our phones plus I added a selfie I took this afternoon. There isn't a pro pic amongst them .

I'm another who just got a friend to take pix for me. I've never had a pro shoot done and like others in same situ was never short of work.

I just had new pro pics taken and put them up on my profile the other day and inquiries have been going up a lot. I really recommend to invest in new photos they do pay off.
