His ideas about series and cohesion are well formed and important. I realised I haven’t really done this in my own photography. YouTube is such a useful classroom. If you have time, you can learn something new every day.

Why cohesion matters
A series gains impact when the images feel like they belong together. Repetition and restraint help the viewer recognise a voice across the set.

Unifying levers
Keep a through line in tone and contrast. Keep a consistent colour palette. Repeat a subject motif or shape. Stick to a small range of focal lengths or aspect ratios. Keep processing consistent. Each choice reduces visual friction and builds identity.

Editing down
Fewer, stronger pictures beat a bigger, looser set. Remove images that disrupt the look or repeat an idea without adding something new.

Sequencing for flow
Order the set so one image naturally hands off to the next. Match on colour, shape, horizon line, perspective or gesture. Avoid jarring jumps unless you want a deliberate beat change. Think in pairs and small runs, then refine the whole.

Opening and closing
Start with a clear entry picture that states the theme. End with one that resolves or echoes the opening. Place the most complex images after the viewer is oriented.

Pacing
Mix tempo. Alternate tight details with wider breaths, brighter frames with calmer ones. Give the viewer places to rest.

Project scope
Define a boundary such as place, timeframe, subject or mood so the work stays focused. Constraints make editing and sequencing easier.

Presentation matters
Consistent borders, margins, titles and captions reinforce cohesion when you publish as a page, zine or book.
