This month we’re also running explainer series for Photoshop (which requires a paid monthly or yearly subscription) and Corel PaintShop Pro (which is a one-time purchase of around 70 pounds / 80 US dollars).

The pre-requisities

This is a BEGINNER workflow explainer, so you just need to install and open the software. We’ll take it from there.

If you’re new to IT / computing, you may need help downloading and installing the software. Start with a search for ‘how do i install gimp’ or speak with someone who’s familiar with downloading and installing.

Why would I do this?

Colour correction is used to make images look ‘better’ (Yes, we know that’s subjective!) Workflows range from applying a one-click filter (for example a ‘retro’ or ‘hyper-real’ effect) to adjusting colour curves before printing a photo for gallery display. In this explainer we open a photo that looks ‘flat’, adjust the brightness and contrast and try out the automatic ‘color enhance’ option.

Let’s do it!

Click the play icon to watch this video. Subtitles are available – Click the settings cog at the bottom right for options. You can also watch this video full-screen by clicking the full-screen icon at the bottom right.

Good to know

Most imaging software and apps include numerous one-click filters or ‘looks’. They might be all you need!

Where to next?

Looking at the ‘Colors’ menu, you can see there are many additional options to try out. Feel free to play around with them. For example, shown below are the changes you can make to the HUE & SATURATION of an image, which are used to adjust colour casts or add warmth/vibrancy to an image. Remember you can use UNDO if things go wrong.

Remember, this is part of a series of explainers for this software – Join us again for the other explainers in the series 🙂
