I recently did a hipster-style walk-through of a public place, taking snapshots of the people and activity with the Olympus XA1 held at hip level, with image framing done visually without looking through the camera's viewfinder.
The resulting images are quite interesting and diversified. While some are sharp and properly framed, others turned out unframed, unfocused, and blurred by camera and body shake. Getting these images together into a visual storyline was done with the tone curve tool in post-processing.
The Tone Curve tool, as available on Olympus Viewer 3 (OV3) as well as most image editors, is a graphical representation of the tonal range of your image and the tool allows you to manipulate the brightness and contrast of the RGB color gamut of the image or the individual red, green and blue channels by picking the color separately from the drop-down list.
The tonal range of an image can be changed by first placing cursor points on the diagonal representation of the image and then by dragging the points up or down from their original location. The line can be removed at multiple points along the line for varying results, and curves are controlled by using several anchor points placed along the line.
