ok i dont want to burst any bubble but i really cant and wont take credit for perceived technical skill that wasnt really there so i'll tell you the story of those 3 shots
I did maybe 15 shots, all just randomly shot from the hip on the tube that day. I was hoping for 2 or 3 single shot candid portraits. I just feel so awkward and intrusive lifting a camera to my face to shoot people out in the wild so feel much happier just firing random shots. Anyway. other than those 3, all the other shots were blurred , shaky shots of peoples shoes, bags, poles. The last shot was , luckily, perfectly in focus. I pre focus the lens and then just shoot away, adjust the focus a little more and shoot more. All from the hip, im not even looking at where the camera is pointing here, im just moving the focus barrel a few mm in between 3 or 4 shots, im trying to blend in and look like im not shooting people on the sly. But i got lucky with the last one. I actually really like the cropping when i straightened the images out, to keep the frame ratio, i love the way the last one turned out and its far less jarring than the other 2 which only took slight rotational adjustments. Something im going to do more of in future for sure. The "canon" seems to be to keep a perfectly framed, rectangular image. But i just love the angles left behind from the straightening.
So when i dev'd them up and had a look through it was only then , in an attempt to recover something out of the mess, that i thought of the triptych and put these 3 together. It does make sense to have them in a set and i can make a story of each frame. The end result worked. But at the time there was zero skill involved, i was planning on single candid frames if i was lucky, something totally different to what i ended up with.
So there you go, what i think was a lucky recovery from a batch of true randomness. But ill be back doing it again and again as the results pay off if you get lucky
The vision and creativity came very much after the event.
Someone above mentioned AA saying 12 a year is good and doing multiple exposures to get a right one. Ive got close to 10,000 images in lightroom. Of those i consider 100 to be worth repeated viewings, of those i have 3 on my wall framed up.
*edit* actually im just trying to work out how you make a proper tryptich in PS as id like to see all three together. The different frame sizes is making it tricky though.
