Hi guys, a real newbie at photoshop here. Was just wondering how i would go about replicating this picture to make it different colours, sizes, transparent so it will nicely fit on a darker background without the pixelation. thanks in advance
Try selection tools, like magic wand, and lasso/magnetic tools. You also need to learn about layers, and how to properly use them. What colors are you wanting the picture, and what are you wanting transparent. On layers, there is also an option to edit blending options. Blending options gives you a pretty wide variety of styles you can use. To access that you should make a selected layer, then right click the layer in the layer box, and click blending options. Hope I was helpful.
If you want to recreate this "without pixelation" you need to use a vector based program like Adobe Illustrator, or a freeware program like Inkscape.
Otherwise you can follow some some of the tips Carson suggested to alter the existing image.
Post any additional questions you have we'll be glad to help you out.
