Well you can try the photo editing tutorials on http://www.gimp.org/tutorials/ .
Also you should definitely download FXFoundry for GIMP, it has alot of easy-to-use filters for photo editing.

For noise reduction, nothing beats anisotropic smoothing in my opinion. It's a filter included in G'MIC (free download, you can google it), and it really does the job well. De-pixelating is .. hard I'd say. But there's a lot of good photo enhancements tutorials on youtube or the various Gimp sites in the web. A quick search will certainly get you some good results in those fields.

By the way, I've got a 5MP cam on my phone as well, and I'm more than happy with the results. It's not the resulution, it's the camera's quality that sets the quality of your images ;) 5 MP is 2984 x 1680 pixels in 16:9 format if i remember correctly. I don't think you need bigger images unless you want to go into really good photography (and by that point, an expensive camera is needed anyway).

thank you oh so much guys/? i found one tut before i posted this original thread last night/moring that somewhat helped and as i was messing around in gimp i came across the anisotropic smoothing. it worked great, thank you arzo :) ... as for the FXFoundry, i see the 2.6 but not a more recent one... is there a newer one? if not could i still use the 2.6? if so how to i load it to work in the new gimp release?

Check this: viewtopic.php?f=31&t=12086 I recommended it a couple of days ago, Maffes post tells you exactly where to put it. And yes it does work with 2.8(atleast for me :-* )

lilredhalo, post some of your pictures and let's see what we can do with them. I think it would be interesting to try to retouch your photos and then explain how to do it. It would make a personalized experience for you and provide us with some entertainment.

Here's my changes.

Image

1. Added an alpha channel so the base layer has transparency. Layers > Transparency > Add Alpha Channel.

2. I duplicated the layer twice. I set one of the duplicated layers to Screen and I set the other to Overlay (can be done by selecting Mode: Normal in the layers dialog and changing the mode). I adjusted the opacity of each layer to about 30-60% depending on what I thought looked best. Sometimes I duplicate the screen layer twice to make it even more bright.

3. I used the FX-Foundry plugin and under FX-Foundry > Photos > Enhance I ran Eg ISO Noise Reduction and Eg Recover Shadows. I may have also used EZ Improver though I'm a little fuzzy in my memory on that detail. Here's where you can get the plugin from...
http://gimpfx-foundry.sourceforge.net/

4. I right clicked on the top layer and selected New From Visible... This created a layer which combined all of the changes I made into a single layer. On this final single layer I performed step 5.

5. I further enhanced the image smoothing using the G'MIC plugin. I used Enhancement > Smooth[anisotropic] and set sharpness to 0.84 and anisotropy to 0.18. The rest of the settings I left default. I didn't know the values to use, I just played with the sliders and decided on what I thought looked best. You can download G'MIC and place it in your plugins folder.
http://gmic.sourceforge.net/

Since GIMP is available for so many platforms the plugins appear to have several downloads for the same thing. Just be sure to pay attention because they are separated by platform. You need the G'MIC plugin for Windows if you're using MS Windows.
