Introduction
GIMP (GNU Image Manipulation Program) is free to download and use at the following link - choose Download GIMP Directly:
https://www.gimp.org/downloads/
Product photography is an art and a profession in itself - pay a professional if required.
Tips for D.I.Y. for smaller products. Use a bright natural daylight source e.g. in front of a large north facing window to avoid strong shadows from direct sunlight. Use a uniform background or backdrop e.g. a plain sheet draped from horizontal to vertical. The photographs may not be perfectly exposed or perfectly framed but that can be changed using the software.
- Open GIMP.
- Open your photograph - go to File → Open... or Ctrl+O on keyboard.
Exposure
- Adjust exposure if required - go to Colors → Exposure...
- Use the Exposure up and down arrows or slider to adjust and preview.
- Click OK
Framing, Cropping
- Adjust framing if required - go to Tools → Transform Tools → Crop
- Click on the image and drag the cursor to select a crop area.
- Adjust the crop area and click Enter on keyboard.
Resize, Scale
- Resize (scale) your photograph - go to Image → Scale Image...
- Images for website should be about 500px - 800px
- Enter a value for either the height or the width and the other will change accordingly.
- Images for website should be 72 pixels/in per inch so change the value.
- Click Scale
- Ensure view is full size - go to View → Zoom and adjust to 100% if necessary.
Format
- Images on the website can be any format e.g. landscape, portrait or differing ratios but it is advisable to make them all the same by adding a background or canvas - square works well. Your original photographs may all be different formats and ratios but the canvas can be used to fill the space around them to make them the same.
- Change format - go to Image → Canvas Size...
- E.g. to make the image square, change whichever is the smallest dimension to the value of the largest.
- Click Center
- Choose Background color from the Fill with: drop down menu.
- Click Resize
- Alternatively, if the background of your website is a different colour, set this colour as background colour first.
- Go to Tools → Toolbox
- Click the background colour.
- Enter the hex code of the website background colour in the HTML notation: input box
- Click OK
Optimise
- Optimise and save the image.
- Go to File → Export As...
- Enter a new name in the Name: input box - use lower case and hyphens - instead of spaces including the file type. For example, your-image.jpg
- File type is a choice. Either .jpg or .webp are advisable.
- Navigate to the images folder/directory in your backup on your computer in the navigation panel and save there for use in your project.
- Click Export
- Tick the Show preview in image window box.
- The File size will then show.
- Images for website should be less than 100kb for fast loading.
- Use the Quality: up and down arrows or slider to reduce the file size down to less than 100kb.
- Check the preview of the image to ensure image quality is acceptable.
- Click Export
