Dealing with noise the smarter way

You noticed a bear inside a cave just before evening. You recall seeing a duplicate of this shot in the last National Geographic magazine. You bring your thousand dollar camera up with a proud telephoto lens sticking out a couple feet and set ISO to 200 only to find shutter speed showing 4 seconds. Okay, no problem, Set ISO to 800. Still a shutter speed of 1 second. But the bear is licking its belly. Stock photo sites usually don't tolerate tongue blurs. No worries. ISO 25600. Now you got a shutter... continue reading

Noise Reduction Tools: A Review

As a photographer, you always get to encounter situations that are worth capturing but the light is extremely unfavorable. If you have a tripod, you are good to go. But that doesn't always help. Recently while trying to make an HDR of a church interior, I wasn't allowed to set up the tripod because it would obstruct flow of tourists. The church was beautiful and I wanted an HDR, whatever happens. So I had to step up ISO to 1600 (still got a shutter speed of around 1/13 only). Thanks to Canon's outstanding... continue reading

Vibration Reduction or IS

Wondered, why VR (Vibration Reduction) had different names and were little, confused when I saw that there were different names on different brands. so I googled a bit and found this!Same technology, different brand names.Pretty much the same technology under different acronyms.....probably due to trademark infringementVR (vibration reduction) is Nikon's trademark name for stabilization. Canon's is IS or "Image Stabilizer. Same thing from different brands.Canon Image Stabilization IS... continue reading

Sometimes you want to see if a photo was taken with VR On or Off. Usual image editing or viewing software don't show this.This is how I do:- Download Exiv2 from here:- Windows version is here:- Unzip in a root folder, I put it in C: because you will have to write a command line in Command window and will be easier.- Copy your photo in that folder.- Start - Run - Command to open the black Command window.- Make sure at your cursor is C:> then type: cd exiv2then type: exiv2.exe -g... continue reading

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

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

Colour shift in images after noise reduction in Noiseware

I experienced a colour shift/saturation drop in my photographs when I processed them using the noise reduction software, Noiseware. The original images looked fine after converting to JPEG from the RAW files, but there is a significant change in colour/saturation when opening the JPEG/TIFF files in Noiseware. I realised this only after upgrading the Nikon ViewNX software to the newest version of ViewNX 2.Read on to find out how I managed to resolve the issue :)http://www.truphotos.com/2010/10/... continue reading

Noisy photos ..

Had a bit of a problem myself .. too much noise in the photos.I thought the lens I used was at fault but a friend nicely showed me a few things I didn't know.This is gonna sound stupid to many of you but I'm sure quite a lot of newbies throwing themselves into stock photo would have done the same...The ISO action on my Nikon D90 I try to lower at 200 ISO but for some reason if the Auto ISO settings would always put it up quite significantly.What I'm trying to say is there are many many options... continue reading

Getting the most out of your gear - Noise

Photographic gear, of course ;)Maybe the professional doesn't need to worry that much about grain/noise. Modern and professional (expensive) cameras create noise free images on most situations ...But I do worry about it, I can't afford top quality hardware so I have to work with what I have.
