Curves come in different shapes but the two to remember and use are the C and S curves.
'Using Curves in your Photographic Composition' by Geoff Harris

What else to add? Implied curves are fine too.

How to Create Compelling Compositions with Curves









Photos for the Week #4 competition are to be taken between Mar 2, 2020 and Mar 8, 2020.

Rules:
1. Anyone and everyone who is interested in eligible. The goal continues to be
have fun and share comments, concepts, insights, and techniques with fellow
Pentaxians.
2. Each week will feature a Theme and Sub-concept for you to explore.
3. Post your single picture in Project 52-5 thread for the week. Explain what
motivated you to take the picture and/or how you feel it represents the weekly
theme.
4. Some post-processing is OK (adjusting white balance, exposure, color
saturation), but let's try to stay away from heavily PP'ed images here. Try to
keep the creativity to photographic techniques and the captures themselves.
5. Since this project is about technique, and not camera, shots taken by non Pentax cameras are allowed.
Cameras may be SLRs, DSLRs, Point & Shoot, Medium Format, et cetera. But no phones, please.
6. There is one “Theme Concept” labeled “black and white,” but feel free to post
black and white, sepia, monotone, etc., for any of the other themes.
7. The picture you post should be taken during the week in which the theme is
active to be eligible for judging.
8. Any picture taken from thread start date to listed closing date is acceptable
