Landscape and Lumps
Hello Forummembers,
(hope this is the right section for this question)
I've studied the tutorials, learned a lot and try to apply my new knowledge. It's my goal to finally be able to creat great landscapes like most of you show us here.
There is however one problem I encounter most of the time; lumps and unwanted grain in the sky area.
When I convert (usually using Chanel Mixer) I get lumps or grain mainly in the sky area when I'm adjusting Red, Green and Blue.
Also when applying USM Contrast the same seems to happen in the darker area's. In most of your landscapes I see beautiful deep black skys, how does one achieve that ?
Recently I started using a trypod and combining several RAW files together; I have to say the result is much better, but does this mean that creating a higher dynamic range from only one single RAW file is never goiing to work ?
Or can one not live without Noise Ninja, in that case I should buy it right away ?
(by the way; I shoot with an 350D and try to keep ISO as low as 100, sometimes 200)
Thanks for your support on this !
Leon

Re: Landscape and Lumps
Hi Leon...the unwanted noise in the sky is a problem for all. Multiple images, whether for HDR or just averaging should reduce the noise but usually if you want a smooth sky some third party product is required such as Neat
or Noise Ninja
...they are both the best because they say so!
If you look on this Board you do see that the Canon users appear to have better control over sky noise so Karl, Steve and Martin and others may give you more specific tips to the kit you use...

Re: Landscape and Lumps
Hi Leon maybe if you posted a crop of this effect to show us, using the 350d at iso 100~ 200 there should be no noise,noise is always more apparent in the shadows of under exposed areas, if your skies are not under exposed then I suspect it in the editing and the over usage of USM, this does tend to clump areas and give that lumpy look, in all my tutorials on using it I do say use it with caution as it can destroy pixels, as I say post a crop of this and from that we would be able to tell what your doing wrong

Re: Landscape and Lumps
Hi Martin,
Thanks ! I will send an example soon. There's no problem with the camera when shooting 100 or 200 ISO. The noise is generated during my workflow, I think I do too much and expect too much (as you already suggest).. As it is; I'll post an example in the next few days, Thanks, Leon

Re: Landscape and Lumps
Dear Forummembers,
Ok, here are two examples. I used two different exposures from one RAW file and started using the techniques described in the tutorials. In the second example my main goal was to get a deep black in the sky, I think I asked just too much from my and Photoshop's capebilities..
I might just simply have to grow more patience and practise more but I'm happy to realize your knowledge is there to benefit from ! I tried using a tripod this week and feel this works better, multiple RAW files seem to improve the result, although there still is some unwanted grain here and there..
Thanks, Leon

Re: Landscape and Lumps
Looking the the examples you have posted the problem you are experiencing is underexposure in the deep blacks, this manifests its self as banding, as you have said the editing has caused this as you are trying to achieve a maximum black when its not possible using the file and info within, in other words your trying to go to maximun black when the tone is more in the mid section of the grey scale, I would try to alter your exp technique to give deep blacks by using the multi exp tech and exposing for the sky using a metered exposure , also it really does help to use a graduated grey grade filter to give the file information to work with by deepening the blue in the sky

Re: Landscape and Lumps
Thanks Martin, Glad to understand what I did wrong.. I had a look into these filters. I saw there are a several possibilities; a fixed type one simply screws on the lens and a more flexible type (Cokin f.i.) wich I think might give more answers to different lighting conditions. Wich one is the best to use ?
Kind regards, Leon
