Wow! Simple and yet extremely effective at removing the noise from the original image. This is the result (move the mouse on and off the image to see the comparison image in place JavaScript required): I followed the five simple Neat Image steps: open image, use Auto Profile, use default Noise Filter Settings, Preview, and save the image, as seen in these screen shots: The raw image, 5 minutes, ISO 6400, had been edited in Aperture and saved as a JPEG. This is the version I originally posted on my Cassiopeia Observatory web site. Since it was cloudy, I couldn't take any dark frames (which Neat Image can use) or new images, so I decided to use one of my older Nikon D7000 DSLR Deep Sky Object astrophotographs taken through my Meade 8" LX200-ACF as an example image. So, before delving into the User Guide, I had to try it myself. After reading the Quick Start Guide, I said to myself, "it can't be THAT easy". It was cloudy anyway so this gave me an opportunity to learn the application. RAW images can be processed after they are converted to TIFFs (using TIFF is recommended to avoid quality loss due to compression) or to JPEGs (this involves quality loss, because JPEG is a lossy format).Īs I do with all software (and hardware), I first read the documentation. TIFF (singleimage, nolayers, noalphachannel, nomask).Some features are only available in certain editions of Neat Image. Preview of filtration results separately for each channel and frequency component.Embedded preview for any selected image area.Background processing: multiple images are processed in background as you prepare new images or work in another application.Batch functionality to process many images automatically.Batch profiler to automate profiling with the Calibration Target.Auto Match to select the most suitable pre-built noise profiles for input images.Rich set of pre-built noise profiles in the online profile library.Auto Profile to build noise profiles for your camera or scanner on the fly.CUDA-accelerated filter to speed up processing using computation-capable GPU.8-bit, 16-bit and 32-bit image support to fully utilize capabilities of modern image acquisition devices and support HDR post-processing workflows.Smart sharpening filter to make images look sharper without amplification of noise.Complete control over the filter settings to achieve the desired level of noise reduction.Advanced noise filter to reduce noise and grain in digital images.Neat Image has these features (from the User Guide): Noise Reduction and Image Sharpening The free "demonstration" version is fully functional, with only a few limitations.) I also downloaded the Quick Start Guide and User Guide from the Neat Image web site. (By the way, "Demo" is somewhat of a misnomer. I downloaded and installed the Mac OS X standalone Demo version. Each version is described on a Neat Image feature map (link to the Mac standalone version). It is available in plug-in versions for Apple Aperture (Mac OS X) and Adobe Photoshop (Windows and Mac OS X), and standalone versions for Mac OS X, Windows, and Linux. There are three versions of Neat Image: Demo, Home, and Pro. I have tried using the native Aperture noise reduction but have always been disappointed with the results. The Neat Image web site even mentions "astro" imaging. The tweet claimed that Neat Image was a great noise reduction tool. I recently heard about Neat Image via a tweet on Twitter.
