Antonio Lambe Posted Wednesday at 11:15 AM Share Posted Wednesday at 11:15 AM Apologies if this question has already been submitted. In a rectangle, or, better, a polygon at the top of a dawn photo for the portal of a website I want to implement a lightening gradient to set off the site's logo. Any fool-proof instructions for how to accomplish this will be deeply appreciated. Thank you. Quote Link to comment Share on other sites More sharing options...
frio Posted Wednesday at 12:05 PM Share Posted Wednesday at 12:05 PM Make a black & white gradient-filled shape on a separate layer and set the layer blend mode to Additive, Color Dodge, Lighten or Screen to create a lightening effect. To make a basic linear or radial gradient in a shape, use the gradient tool to draw the desired gradient and then select the shape you want on it, invert the selection and delete the parts outside. A simple linear gradient cut to an angled rectangle in color dodge mode: To create a gradient conforming to a shape specifically, you could try TR's Contour Filler (simple, not so accurate) or G'MIC Rendering->Gradient (custom shape) (more complex, more accurate). Star shapes filled with G'MIC, original on top left, other blend modes in the order mentioned above. Quote Link to comment Share on other sites More sharing options...
Antonio Lambe Posted Wednesday at 05:07 PM Author Share Posted Wednesday at 05:07 PM Many thanks, Frio, for the prompt and promising reply. But you have generously assumed I know a lot more than I do. I presume one must first go to Layers > Add New Layer which I have apparently done. To "Make a black & white gradient-filled shape on [this] separate layer" must I then use the Rectangle Select or Lasso Select tool? Below is the result although the lasso seems to have disappeared. As for the further instructions, I'm afraid that without step-by-step novice instructions I haven't a clue how to proceed. And perhaps this is too much to hope for.

Antonio Lambe Posted 17 hours ago Author Share Posted 17 hours ago My efforts with Paint.Net, below, to lighten the sky have proved very clumsy and the transition looks so artificial. Any simple pointers for achieving that effect would be much appreciated. Thank you. Quote Link to comment Share on other sites More sharing options...
Tactilis Posted 14 hours ago Share Posted 14 hours ago @Antonio Lambe it would make it easier for people help you if you posted: 1. The image of your logo. 2. A version of your original photo with the logo overlaid so we can see the size and positioning you are aiming for. Don't worry about the gradient at this stage.

Welsh Yellow Cheddar Posted 9 hours ago Share Posted 9 hours ago @Antonio Lambe There are probably many methods of achieving this. I would just reduce the opacity of your image and add a white layer below it. To keep the dark trees I would create a mask and place it at the top. You can also tint the sky with a color gradient of your choice on a layer with multiply mode. I hope this helps. Quote Link to comment Share on other sites More sharing options...
