Note: Pixlr will automatically save the image resolution at 72 dpi.

Resizing Images

Pixlr

Colour Models:RGB and CMYK

Rules Of Thumb

1. Begin with the highest resolution and best picture you can.

I often then work on a downsampled copy, so that I always maintain the original.

You can’t “add quality”.

2. Choose the “right” format and tools

3. Consider the various destinations for your image

Print

​

Poster?

Paper?

RGB/CMYK?

Billboard?

Postcard?

​

Web

​

Article?

Social media?

PDF?

​

Mobile

​

Home?

4G?

Other?

But don’t be too obsessed, there are many more resolutions/dpi, many print services can handle RGB images, and there are tools to help with all of this.

4. Use Sensible Names - Get Organised
