Now that we've gone through all this work it wouldn't be complete without your logo now would it? We are going to keep the example simple using my favorite logo of all time, mine of course! If you have a pre made logo just simply size it down to about 200 pixels wide, set mode to grayscale, copy it, then paste it into a new document. Set the canvas size to match the dimensions of your dish, in this case 290 x 340 pixels. We want to add a slight curve to the logo so it looks natural sitting on the dish so move the logo to the approximate position it will be on the dish and run Filter -> Distort -> Spherize with a setting of -40. Now copy your logo and paste it above the dish layer and position it at about the center top of the dish and lower the opacity to about 70% to allow the shading and texture back in. Finally for an added touch we will add the 4 screws that attach the satellite dish to the base. On a new layer use the circle tool to create a small circle at about 10 pixels wide. Add a bevel and emboss style set at about side 3 and pillow emboss and then adjust the fill slider to 0. Copy that layer 3 times and arrange them in the positions shown in the final image. It's time to add some color so add a hue/saturation layer above the others and set hue to 200 and saturation to 20 with colorize checked. Finally create the shadow by selecting all the pixels outside of the dish using the magic wand and inverting the selection. On a new layer under the others fill the selection with black. Choose Edit -> Transform -> Distort and drag the shadow around until it looks natural, then add gaussian blur of 5 pixels and lower the opacity to 50%. The final image on the right shows our satellite dish showcased on a nice background. Hope this tutorial gave you some ideas for your own projects. See ya next time!
There you have it. This image data is in 30m data. This means that each pixel represents approximately 30 meters length. Not really good, but does well for large areas. This can be improved upon by using Band 8, the panchromatic band, to effectively double the resolution to 15 meter. I outline the methods in the next tutorial: Doubling Landsat-7 Image Resolution.
