    Yep, loads of it. Mostly in run-down areas/buildings as you'd expect. :p

    In my edit of Crotale's shot there is quite a bit of luminance noise. I removed the color noise you have described. Crotale underexposed his shot by about 1-2 stops. He should have taken the shot at an ISO of 400 instead of 100 for correct exposure. Sometimes you don't think or notice these things. When the exposure was compensated in post I lost a lot of dynamic range in the blacks. Most of what you see is just fog, some is a clipped blue channel, the rest is me trying to create more dynamic range than was originally captured through various mask layers.

    I wasn't there to take the photos so my interpretation of how things looked can be skewed and viewed as more artistic than real.

    This is exactly what I'm talking about in reference to learning how to use the camera and to make the best use of lighting, DOF, etc. Until a month ago, none of that stuff mattered to me. And it frustrates me that I cannot get it right, but it's only been a month and I've only taken about 700 or so shots with the Alpha.

    Utterly sh*t cars. Par for the course for Chrysler. I got to drive one a few times. Worst car evar! Looks neat on the outside but it's crap on the inside, ridiculously uncomfortable, and doesn't drive like a sports car. I'd pay more for a Mazda 3 than for that turd. :lol:

    I understand. This isn't criticism of any kind. I'm just a bit frustrated about otherwise great looking pictures turning out bad because of this.

    So choosing exposure time can avoid this ? I can understand what's happening in a dark scene but what about the picture of the mountains ? Is that due to strong ambient light ? There's also the occasional red line that can appear if the sun is in the picture or if there is a very bright source of light.

    Wow, you're a master of psychology! That's an incredible analysis for somebody who doesn't have a clue about the situation :D
    Maybe I'll post a thread about it all some day, and then you'll understand it's not always that simple.

    Same here, they look cool but are nothing special otherwise.

    LOL, it's probably an operator induced error. You don't even want to see the pictures I won't share.

    Edit://I hope this early morning sky shot turned out okay. It was so weird that just yesterday, there were no clouds to found and this morning, all I saw were clouds in the sky. I sharpened this a bit in Lightroom, but this is pretty much how it was shot.

    Correct exposure can really help out! It took me almost a half a year with my 20d before I could simply look at the LCD on the back of the camera and know for sure the image was correctly exposed. You have to really pay attention to the subtleties.

    It's not an exact science as your camera can give you conflicting info:
    - Light meter says its correctly exposed
    - Levels say its correctly exposed
    - LCD looks correctly exposed
    - When opened in post it isn't exposed enough causing lots of noise.

    There are a few tricks you can use to minimize noise and maximize dynamic range making your images very colorful.

    Many photographers feel the need to underexpose by a 1/3 stop or more just so they don't blow out important highlights. While that is a great technique it simply creates problems in post. Should the photographer choose to increase the exposure in post it will introduces more image noise and takes away from the shadows resulting in flat or clipped shadows. There is clear evidence of this in the mountain raw file. I attempted to fix by use of dodge and burn along with other techniques with enhance dynamic range. You cant create detail where there isnt any, you can only enhance what is already there. In other words.. I cheated :)
    Solution?

    Overexpose! .. but only slightly. Raw lets you do this and the rewards are great. Raw allows 1 stop of safe recovery of either highlights or shadows. Some cameras will allow more (more at lower ISO, lower with high ISO). This means that you can safely recovery detail of over or underexposed areas without issue. Most of you already know this :) What you probably didn't know is that if you reduce your exposure in post you are suppressing your image noise levels along with your exposure resulting in a more pleasing image. Don't believe me? Try it! You will notice more detail in your shadows and less image noise over all.

    Red line? Could be a flaw in your sensor. I know a few sensors out there that produce strange results when intense light is introduced. Nikon D70 makes a green line. Nikon D200 has a pseudo interlaced effect on edges. You should see if the flaw is well documented and what to do about it. Your camera may need to be serviced. Sometimes a simple firmware update fixes the problem.

    I tend to under expose quite a lot of the time in order to get a better shutter speed and a sharper image. Depends on what I'm trying to do though, now its starting to be brighter weather I haven't been needing to do it. :p
    I seem to have to underexpose with my Sigma 30mm particularly as the camera doesn't seem to meter correctly to my eyes :p (atleast on the LCD it looks off)
    I've mostly used this lens in dark enviroments at ISO 1600 anyway, so under exposing just makes it easier to get a sharp image :p

    Need more time so I can experiment properly :p

    So in all likelihood the husband of the woman you're dating has turned into a demon zombie mage and is refusing divorce. You are a very brave person.

    Surprisinly more then half of the people that see that photo have to be shown the spiders. They just think it's a wierd flower.

    Well actually there are 2 spiders in that pic... A bright yellow crab spider and 1 I don't recognize. I think 1 is about to be lunch for the other.

    Don't know why but I like pictures of bugs..
