# Posted: 26 Aug 2006 23:08:44 I have a Sony Ericsson z300a and I am trying to make my own wall papers from pictures on my computer. I changed the image size to 128 X 128 and 100dpi on jpg at the max quality. Uploaded it to a webpage, and send myself a text message with a link to download it. I get the picture on the phone, but it does not look as sharp as the ones that come with the phone. What I am doing wrong? Thank you. |

# Posted: 16 Mar 2008 12:07:52 I don't think dpi has much to do with it, I think that's more about printing an image to paper. You phone will display a particular resolution at a particular color depth. Most newer phones easily handle 16 bit RGB (high color) pictures at 65,535 unique colors contained within the phone's graphics display palette. When you load a jpeg file that contains millions (up to 16) of colors the phone may dither those to simulate the image's color palette the best it can. This may cause the image to appear "grainy". If it's not dithered it will appear striped. http://en.wikipedia.org/wiki/RGB#16-bit_RGB_.28Highcolor.29 http://en.wikipedia.org/wiki/Dithering#Dithering_examples As far as the sharpness goes you my be better served to download an image that's larger than your phone is capable of dsplaying to your computer and use a program such as 'PhotoShop' or 'Paint Shop Pro' to resize to the proper resolution. Your phone may not be that good at resizing on demand or formatting during upload/download. Personally I use Paint Shop Pro, reduce color depth to 256 using "Optimized Median Cut". You really should avoid "web safe"... If you can't resize to your phone's exact resolution, resize as close as you can to height or width and copy it. Create a new file at the proper resolution and paste the copy as new selection. You should be able to adjust it, either having a border on either side, top or bottom or give up some of the picture you want so you see the main subject. Hope this helps! |
