"Advanced" image processing
Just curious if anybody knows techniques to substantially enhance images
taken under bad lighting or weather conditions. For instance if you shot photos on an overcast, dark day, if there is a way to make these photos shine. Would it be possible to transform an overcast sky into a nice blue sky? Or if you shot images under hazy conditions, with poor visibility, would it be possible to give these images "vibrance", good contrast and colours and if so how? -- Alfred Molon ------------------------------ Olympus 50X0, 7070, 8080, E300, E330, E400 and E500 forum at http://tech.groups.yahoo.com/group/MyOlympus/ Olympus E330 resource - http://myolympus.org/E330/ |

You can replace the whole sky with Photoshop! You can adjust the heck out of everything! Post-processing is as big as photography, if not bigger. |

There's a subtle line between truthful photography, artistic rendering. Both take skill. -- "As democracy is perfected, the office represents, more and more closely, the inner soul of the people.

It is possible to improve the color and balance on images like this, but only at the expense of reduced sharpness and increased noise. Look at the image adjustments menu in PhotoShop. Start by playing with the curves and levels controls. |

Not really photography at that point, more like image molestation-bordering on rendering.

That's why I settled on being an engineer. I'm also not quite smart enough and/or too lazy to lie. Lying takes too much mental effort. Lies are like economies, and need constant compounding. Hence most of my photo work really is pretty straight, simply because I don't know better and can't imagine a suitable embellishment for the reality. I'm not above doing a few helpful touch-ups here and there, though. rafe b www.terrapinphoto.com |

My own feeling about editing images is that it's as much an
art form as photography or painting - just different. Or maybe not so much different as combining the two. The only problem comes in when someone pretends an edited image is not edited. But this topic has been argued to death in this newsgroup. Here's some practical advice: 1. If you haven't got $600 to burn on Photoshop, there are cheaper ones that will do what you want. The one I use is the GIMP - a totally free, open source image editor that does a great job. See http://www.gimp.org 2. Simple image editing is often very easy. Sometimes there's just one button to push to "auto-enhance" the color of an image, or very simple controls in "curves" or "levels" to correct contrast, haze, and other problems. 3. Sophisticated image editing is very hard. There is a huge amount to learn and a lot of it requires hours upon hours of trial and error learning to see what the effects of the controls are. Experts may think nothing of putting many hours into a single image. Alan |
