Cutting out the Noise

I have just received word that Topaz are launching a new version of their DeNoise software tomorrow. As an existing user I receive a free upgrade and wish more software companies would follow this model. If you don’t own the software its priced at $79.99 but if you use the discount coupon code “NOISEFREE” when checking out the price is reduced to $49.99 until the 20/03.

You can use this link to reach the product page of the Topaz Web Site.

I have been playing around a little with a Beta version and I’m quite impressed. Take a look at the following comparison – be sure to click the image to see the enlargement. This is a section of an image viewed at 100% magnification and was shot with a Sony RX10 at ISO640. The top image is unfiltered whilst the lower one has been processed using DeNoise.

ISO640 after DeNoise has been applied. Yes it's also sharper as there is a deblur option.

I’m going to investigate this further once the full version is out tomorrow.

LX5 Essential Accessories

Brooklyn Bridge in New York. Shot with an LX5 and processed in Lightroom with Nik Dfine and Silver Efex Pro 2

I don’t normally like carrying too many accessories for my photography because they can be a bit of a double edged sword. On one hand they help you do things that wouldn’t otherwise be possible but on the other they add size, weight and can hinder your work. There are some accessories however that I do consider essential for the LX5:

  1. Screen protector – I don’t think this one takes much explaining other than to say the rear screen can scratch easily. I use a 3 inch thin plastic screen protector that was made for a mobile phone as they are cheap and do a great job.
  2. JJC lens cap – Where the LX5 lens meets the camera body there is a threaded ring. Unscrew this ring and you can screw on the JJC replacement lens cap. The lens cap is never removed but as you switch on the camera the lens extends through the lens cap which splits into three. When the lens retracts the lens cap closes to cover it again. This has protected my lens on countless occasions and also reduces lens cleaning. This is a great accessory for street photography.
  3. Filter Tube – In the previous point I explained how the filter cap could screw to the lens of the camera. The filter tube follows the same approach and screws to the camera with the lens extending inside the tube. The other end of the tube is threaded and can accept a filter ring to which you can then attach filters. For Landscape Photography the ability to attach an filters such as an ND Graduate is essential. The only downside is that you can only attach either the lens cap or the filter tube but not both together.
  4. My final accessory is really optional and is noise reduction software. If you are keeping below ISO400 with the LX5 and not printing larger than A3, you probably don’t need this but as the ISO creeps up it can become essential. Even if you use only low ISO settings you may be a bit of a perfectionist as I am (I often clean images even from my 5D MkII to remove noise because I am that fussy). I actually use 2 software packages for noise reduction at present, Nik Dfine and Topaz DeNoise. DeNoise is probably the best to my mind but you might have your own preference.

On a final point of interest, many photographers would consider the LX5 to be an accessory for their main camera. If you are one of these people think again and try a day out with just the LX5 and a couple of accessories.
