Image Editing Tutorials
Here you can add your own or others' tutorials regarding image editing programs such as Paint, Paint Shop Pro, Photoshop, Gimp, or whatever else you may be using. Note that 3D programs that produces 2D images, such as Poser and Daz Studio, have their own section.
REQUEST: Earthgypsy would like to learn how to make imagemaps so that items can use more than one texture. See this page. If you're up to writing something about this, please add it here. Tutorials regarding how to apply textures would be found under the sections for the particular program used. (My handcoding tutorial, found under VRML Code tutorials, also mentions how to use multiple textures.)

For images: When I render an image in poser, I set my render options to make the image at least 700 x 700 pixels and the resolution no lower than 300 dpi. I save the image as either a .png file, if i am going to use it as a layer, or as a .bmp image if it is complete in itself. Sounds like the finished product is HUGE, doesn't it? Well it is. The reason for saving in either of those formats is that you lose absolutely no color and no resolution when you save, unlike jpg which will go grainy, or gif....well...trust me....gif is not for art.
OK, now you have a lovely pic and a massive file. How do you get it down to an acceptable size for CT? First, you open the image in the program you will use to reduce both the dimensions and the file size. I use either Paint Shop Pro 7. Resize your dimensions. If I want to maintain the most resolution and clarity, I try not to reduce the dimensions of the image to less than 500 pixels high. In the same box that lets you resize the dimensions, you should be able to check on the resolution too. at this point you want to make sure it is still at 300 dpi. If it's not....MAKE IT SO in that screen. Once you have reduced the dimensions and maintained the resolution, sign your image. I do it at this point because i frequently do some funky stuff with the layer my sig is on, and i want it to keep it as clear as possible. Now, in PSP, i go to FILE and EXPORT, then use the jpg optimizer. This turns your png or bmp file into a jpg and reduces the file size. It measures the compression by per cent. If you have to go higher than 25% to get the image to less than 40kb, then try resizing the image again to 450 x 450 pixels before you export it. The logic behind this method of rendering with high resolution and converting it to jpg only as the last step allows the jpg to have the optimal color and clarity to adjust from. I think if you look at my images, you will see what I mean. |

If you have read my suggestions for reducing the file size of images, then this will hopefully make more sense. When you are working with an image for a thumbnail, you are often working from a screenshot of your item. In the case of an image, you can use the already reduced and ready for CT version that is less than 40kb. In either case, you are working with already compromised resolution. A screenshot, or your final jpg of your pic weighs in at 72dpi. Before you do any cropping or adding text, first, take the image into the Resize Image screen and INCREASE the resolution to 300dpi. This isn't going to do a thing for how lovely your reduced image looks now, but what it will do is break up those 72 dots per square inch into smaller dots that will allow you to maintain at least the clarity that you already have. Once that is done, reduce your dimensions as needed and add your text, add any other elements that you use for thumbs. Merge your layers, and then go to File, Export, and use the jpg optimizer in the same way I described for the images, below. Consider that the larger you can keep the thumb (closest to 450 x 450 pixels) the easier it will be to read, even if you lose some clarity. Also, the less you have to reduce the resolution in the optimizer, the clearer it will be. Try not to reduce more than 25%, especially when using text. If necessary, take the dimensions down slightly to lessen the amount you have to compress it.
This method works well for me. I hope it works as well for you! |

Easiest way that I use Paint Shop Pro, bring the thumb image up, i keep a 'generic' one of 450 by 450 .... then resize the pic, copy, paste on thumb, put my text on. Next I export as a jpg, save usually between 20 and 25kbs. reopen it, use the 'sharpen' brush, and it makes the image smaller. :) I do the same on pics if they are over 95kbs, as it reduces the image to below the 40 allowed.
