Quick Digital Imaging Tip 25/101: Reduce Noise for Cleaner and Also Softer Images

2 Comments

This is tip #25 of 101 digital imaging tips I plan to post here over the next few months. Stay tuned.

Today's tip: Reduce noise for cleaner and also softer images.

As the ISO increases, so does the amount of noise in a digital image – especially at high ISO settings, and extra especially in low light situations. Long exposures also add to noise in a digital file.

Also, low-end digital SLRs have more noise at high ISO settings than high-end digital SLRs. In addition, compact digital cameras have more noise than digital SLRs when set to the same ISO – due to the smaller size of the sensor.

Reducing noise is easy. One method is to use the in-camera noise reduction feature, but that slows down the shooting rate. A more popular method is to use a noise reduction program or plug-in.

For this HDR image, taken before 6 AM in very low light in a Buddhist temple in Cambodia, I had my 5D Mark II set at ISO 1000. As good as the camera is at delivering low-noise images, the resulting file did have a bit of noise – due to the very low light and relatively long exposure (several seconds).

As an aside, this image looks very soft because there was no direct light – only very soft, diffused, low light. The light level was so low, in fact, that I had to use the LCD illumination button on my camera to check my settings. In this image, the mood and feeling is most important.

I first created this HDR image with Photomatix, and then enhanced it in Topaz Adjust. In Topaz Adjust, I used the Noise reducing feature in that plug-in. It worked quite well at cleaning up the image.

When you reduce noise, you also reduce the sharpness of an image. Check out the image below.
For this image, taken in Bodie State Historical Park in California, I reduced the noise (again using the Noise feature in Topaz Adjust) to the point where the detail in the image was lost – creating a painterly-type image. Try this effect. You may like it.

P.S. A note on noise: My dad used to say: If a picture is so boring that you notice the grain, it's a boring picture.

A Big Thank You To a Great Guide - and New Great Friend in Laos

Comment

I have had many of good guides in my travels to more than 100 countries. My guides helped me get good pictures, imparted their knowledge of the area, and made the experience fun.

On my recent photo adventure to Laos, I was fortunate to spend five days with Vong a thit, pictured here having a Beerlao me.

I could not imagine a better guide. Vong knows everything about the area – culture, flora and fauna, how to get around, etc. What's more, Vong is a very, very sweet, kind, flexible and fun man.

If you plan a trip to Laos, contact Vong at vongla@yahoo.com.

Have a Beerlao with Vong for me!

P.S. It's good beer!

Quick Digital Imaging Tip 24/101: Save Time When Processing Your HDR Images

This is tip #24 of 101 digital imaging tips I plan to post here over the next few months. Stay tuned.

Today's tip: Save HDR processing time by working with JPEG files.

Sure, you should always shoot RAW files - because you can pull out a lot of data from a single RAW file. But when making HDR images, try converting your sets of RAW files to JPEG files before your start processing. I use Image Processor in Photoshop to convert my images. Works amazingly fast.

Working with JPEGs saves you a lot of professing/waiting time. Plus, if you captured the entire dynamic range of the scene in your set of images, you will not lose any details your HDR image – as illustrated by these before-and-after images from Angkor Wat, Cambodia (taken yesterday).

I processed my sets of JPEG files with Nik Software's new HDR Efex Pro. After that, I spiced up the images with the Spicify Filter in Topaz Adjust – which is totally amazing. Info on Topaz here. (Save a bundle by ordering a Topaz Bundle.)

Quick Digital Imaging Tip 23/101: Remove Reality to Create a More Artistic Image

Comment


This is tip #23 of 101 digital imaging tips I plan to post here over the next few months. Stay tuned.

Today's tip: Remove reality to create a more artistic image.

When you remove the true color from a scene, you remove some of the reality. When you remove some of the reality, your picture can look more creative and artistic.

The same is true for sharpness.

Here I used the Midnight filter in Nik Software's Color Efex Pro to create a more artistic image from a shot I took today in Angkor Wat, Cambodia.


Camera info: Canon 7D and Canon 24-105mm IS lens.

This is tip #22 of 101 digital imaging tips I plan to post here over the next few months. Stay tuned.

Today's tip: Play with plug-ins.

Plug-ins – for Photoshop, Photoshop Elements, Lightroom and Aperture – can expand the capabilities of those programs and expand your creative horizons.

Quick Digital Imaging Tip 21/101: Alway Look Up

Comment
This is tip #21 of 101 digital imaging tips I plan to post here over the next few months. Stay tuned.

Today's tip: Always look up (and down and back).

As simple as it may sound, looking up, down and back can yield different photo opportunities, as illustrated by this HDR photograph that I made today in Angkor Wat, Cambodia.

I make this photograph with my Canon 5D Mark II and Canon 14mm lens.

Nik's new HDR Efex pro was used, as well as a touch of Topaz Adjust. (Click here for info on both programs.)

I hope to see some of you at Photo Plus Expo in NY. Here is my nutty schedule. Stop by and say hi!
