This very easy tutorial is meant for those who know nothing about Photoshop, but want to modify the bandlogo without any help, especially from services who charge money for 3-click jobs.
I'll explain how to apply outlines, glows and gradients on your bandlogo in Photoshop. You may use either vector or raster logo for these effects. As image sample we'll be using one of my unpaid/never used logos, which has vector logo layer and raster background fill. Download all Band Logo Samples packed into ZIP archive (How to open ZIP archive).
Open your logo file. Go to LAYERS panel (if it's closed, press F7 or go to main menu and check Window > Layers). Double click on the square with Logo layer. It will open a color picker window, where you will be able to choose the color, but alternatively you can click on the SWATCHES palette (main menu Window > Swatches).
The Color Picker window lets you choose the main color from the vertical gradient bar, where you can click or drag to move the slider up and down. The large square canvas lets you choose the saturation and brightness of the chosen color. When you're done just press OK button.
If you want to know how to change the color fill for the raster logo, scroll down for Gradient fill for Logos - I've explained it there.
Sharp Outline is the best choise if you want to add an effect to small or extra small logo. Other effects usually look messy and blurry, but the outline works pretty good and it's cheap to print.
Open your logo. Change its color to black as mentioned above. still here on the LAYERS panel select your logo layer, then right-click to open context menu. Choose Blending Options to open the window with more layer settings. These settings include almost everything you'll need for basic effects.
Select STROKE from the vertical menu, change the color to white. Size of the stroke for that logo will be about 8px, but always play with it, some logos look better with thicker outline, some look better with thinner. Leave the Blend Mode as Normal, but you might want to play with Position dropdown menu. This option means the outline will be drawn Outside of the shape, Inside of it (will decrease the thickness of the logo itself), or Center (half of pixels outside and half inside).
Glow is probably one of the most often used effect for Metal band logos, especially for t-shirt prints. The main color of the logo is usually the same as background, and the glow is opposite color.
Change the color of the shape to black again. Open Blending Options of Logo Layer via context menu, same as you've done in previous effect. But this time select OUTER GLOW option.
In OUTER GLOW dialogue change Blend Mode to NORMAL, and increase the opacity to 100%. Select white color for the glow effect. In Elements Section use SPREAD 8px and SIZE 13px. For other logo or other size the values will be different, but SPREAD is usually 2\3 of the SIZE for that type of effect. Leave the rest as it is by default.
ADVICE: If you are going to print your Logo, your best choise would be to save it as PDF file as every printing service works with PDF, but some cheaper services don't work with PSD. PDF lets you save all layers and editable text (if there is any on your image). TIFF provides pretty much the same features and very common for most services, so it might be your plan B, if your service has problems with both PSD and PDF. But don't print JPEG, as this filetype provides low quality and non-editable content.
Gradient effects for Metal band logos are very simple and widely used as it's easy to apply and easy to print.
This effect works the same for both raster and vector logos. Choose Logo layer as you've done in previous effects, open context menu and choose Blending Options. Check Gradient Overlay option. For this effect you can leave all the settings by default (or play around with the Angle value, so it will rotate the gradient). Double click on gradient preview to open Gradient Editor.
In Gradient Editor go to the bottom part of the window as we don't really need any presets. Wide gradient preview shows the default gradient applied. Below the gradient preview there are markers filled with color. You can add more markers by clicking below the gradient line. to remove the unwanted marker simply select it and press Delete button (or hit DEL on your keyboard). Drag one of the markers to center and change its color to dark gray (which is #5f5f5f). Small markers are used to control the coverage of the selected color, so you can drag them to make the gray color wider or shorter. Then put two markers at the edges and apply light gray color to both same way you did with dark gray (it's #b8b8b8).
Hit OK on both windows to complete the effect.
If you have a raster logo, to change the color of the entire design you'll have to go to Blending Options as said before, and check the COLOR OVERLAY option. There you'll be able to apply the color to raster image.
