There’s a grid in the middle of the window with a diagonal line going across it. Let’s pause for a second to take a look at this window. Go to Colors > Curves in the Main GIMP Menu.The contrast will make them really pop! Use Curves to Fix Exposure/Contrast in GIMP So, I’ll use a tool in GIMP called Curves to make the beads and the shadows a little bit darker against the white background. It’s bright enough, but there isn’t enough contrast. My picture no longer has that blue tint, but it’s still pretty dull. You may have to adjust the Magenta/Green slider a bit too to make your picture perfect. Then click OK to apply the effect to your photo. Go back and forth between the MidTones, Highlights, and Shadows, tweaking your adjustments until the colors are just right.Check the Shadow option, and repeat the process.Now, check the Highlights option, and do the same thing.(If your photo is too yellow or orange, do the opposite) Then Adjust the Red/Cyan slider to add some Red, and take away some Cyan. Adjust the Blue/Yellow slider to remove some blue, and add yellow.Start with the MidTones option checked.Go to Colors > Color Balance in the Main GIMP Menu Bar.I’ll do that with the Color Balance Tool. Like I said before, this picture is too blue so I’ll need to balance the blue out with more yellow, and even a bit of red. Now, follow along to Fix White Balance and Exposure problems fast! Fix White Balance (color) Navigate through your computers files to find the photo you want to open, then click Open. To do that, just open GIMP and go to File > Open. How to Fix Color and Brightness in GIMP:įirst, open up the problem picture in GIMP. This picture of a necklace was taken on a white background, but it’s easy to see that this background isn’t white! With a little tweaking I can correct the blue tone of the photo and make the beads stand out against the background by adding some contrast. ![]() ![]() If you sell anything online (maybe you’re an Etsy seller looking to up your photography game?) this tutorial is for you! The Problem: Lucky for me, White Balance and Exposure are both really easy to fix in a program like GIMP.Īnyway, since I usually have to correct these two problems, and I’ve seen these problems in a lot of photos on the internet, I thought I would give you the quick run down on how I tackle them. White balance (or color problems) and exposure (or brightness problems). Most of the time there are two problems I have to tackle with my photos. I don’t always get great photos right out of my camera. See? Making a selection go away in GIMP isn’t super obvious, but it’s not exactly hard either. The path will be turned into a selection. Now, if you want to re-activate the selection, go to the Paths Dialog, highlight the correct path, then go to Select > From Path in the Main Menu.Then go to Select > None to remove the active selection from the image.You can dock this dialog to the Toolbox if you want to keep your saved paths handy. You can check that your selection was saved as a path by going to Windows > Dockable Dialogs > Paths in the Main Menu to open the Paths Dialog.To do that, first go to Select > To Path.If you want to save the selection before you get rid of it, you can save it as a Path which you can turn back into a selection later. Alternatively, you can use the keyboard shortcut Shift Ctrl A on a Mac, or Shift Cmd A in Windows.To get rid of the current selection without saving it first: So how do you make a selection go away in GIMP? Simple. In the Channels list, right click and Channel to selection to make a selection from the result.How do I make this selection go away? Once you’ve selected something in GIMP, it’s not super obvious how you unselect so you can do on editing everywhere on your canvas.Use the Threshold tool to remove the gray band.At that point the saved channel is the "active drawable" and so the Paint tools will act on it. Select>Save to channel to save the selection.Layer>Transparency>Alpha to selection to generate a selection base don transparency.Click on the white part (this acts as a "Select by color" on the selection values) and this should restrict your selection to the fully opaque bits.You will get a "negative" of your image (white is what is fully selected, and the "Alpha to selection" selects pixels according to their opacity). Select>Selection editor to open the selection editor. ![]() ![]()
