What is noise and how to handle it? (in 5 minutes ;)

Hi everyone,I think noise (or “grain” as called in the analog photography) is the most common problem of most of us, especially for photographers who work outdoor without artificial lighting. There are many softwares, plugins and filters who try to deal with noise issue and most of us use them as “subtle” as possible, just because whenever you try to clean noise, you clean some of the valuable details off of your photos too...Whatever software you use to clean noise, you should first... continue reading

Goodbye noisy skies with "distorted pixels"!

Hi Dreamers!I guess I am not alone tackling the issue of denoising the skies in outdoor shots,especially when it comes to night photography. Even with photos taken at nominal ISO values (ISO-200 for my camera) I found it often frustratingly noise-prone to make the sky brighter and richer by boosting the levels/contrast.Here are a couple of examples, where my first attempts to "improve" the skies led to refusals initially. That time I knew little about the origin of "distorted pixels" and... continue reading

Preparing Photos for Dreamstime

Before I submit any image to Dreamstime these are the steps I take:1. First I select the best photograph of each subject series based on composition, lighting and sharpness. If it is not sharp already I don’t consider submitting it.2. Next I straighten and crop it in Photoshop to fit the rule of thirds.3. I then slightly reduce the shadows, if necessary using the Photoshop Shadows/Highlights function and a Shadows Amount of around 5-8.4. Next I enhance the lighting and colours... continue reading

Noise Reduction Software

I always had problems when processing RAW image files especially the ones shot at night time or during low light situation.And of course, a lot of it were refused by DT.We all know that we should try to use low ISO setting to lessen the noises, but sometimes we just cant help it and had to increase our ISO settings to get the correct exposure. And the results will more often than not, ended with a picture that is full of tiny grains.I was advised to try and use this software,... continue reading

Images with Panasonic Lumix LX5

Hello!After much research, regarding the purchase of a quality compact camera, my choice fell on the Panasonic Lumix LX5. The key features are: larger sensor than the competition, to keep the digital noise, 24mm Leica lens that starts at F2. To obtain images of good quality, always use the RAW format, JPEG is only for photo-memory, is a little poor. I will not go beyond listing the characteristics of this Lumix, which surely will find it on websites, I leave you with three pictures just accepted,... continue reading

Moonrise, noise and NOISE NINJA...

More than 1 year ago, in April 2010 I took a series of rising moon images just out of my window (near the center of Moscow) with 200mm lens. Then I got an idea to stack them to show the moonrise process.I liked the result but it contained too much noise. Firstly I tried to suppress it with the NEAT IMAGE software but there were too much artefacts after filtering and my image was rejected with the reason "overfiltered". In some months I undertook a second attempt using NOISEWARE PROFESSIONAL.... continue reading

Is the lowest ISO the best?

I have to admit that when it comes to ISO, I've always assumed that the base ISO was going to have the cleanest output.I had read articles on how some models of cameras were noisier at the 'in-between' ISOs (ISO 125 and 160) than the base numbers (100, 200, 400).This was true on a camera I had a while back, so I didn't really give it another thought.I read an article in a magazine (link here) where someone took a Canon 7D with a lens cap on and compared the noise with the levels boosted up.... continue reading

Some trick for noise rejection

Lately I took a set of pictures with night urban scenes. Such a subject requires relatively long exposures and ISO should be in most cases high enough. All this stimulates noise and so, normally night photos contain a good deal of noise artefacts. To supress noise I applied some techinque that I took from my astrophoto experience and now I would like to speak on this matter.1.So, for all my night shots I used tripod and took several shots from the same point and with all the same sets (typically... continue reading
