The smaller stars are totally destroyed in the few images I tried processing.Īfter the positive results with my NGC5566 data I tried the new model on M14. I'm not sure it's an improvement over the previous versions. In the Topaz GUI, the stars develop a slight pixelation effect that resembles under-sampling, and they are distorted around the edges after the image is saved. I tried the newest version, and I found that the Severe Noise model with Sharpening = 0 still chews up the stars, but in a slightly different way. The ability to turn off the AI sharpening completely is huge to me. It's great for dark/dusty nebulae, maybe better than anything else out there? However, I don't want Topaz touching my stars or the midtones/higlights of the image, where the S:N ratio is already good. Generally, I'm impressed with what Topaz can do for problematic noise in the sky background and the shadows of the images. That's exactly how I have used Topaz AI on a few of my images, except I use a 50/50 blend of Topaz and standard noise reduction to achieve a natural-looking result that is somewhat less noisy the the standard NR permits by itself. "I typically apply noise reduction like this with either a mask or opacity of about 80% Leaving 20% of the noise seems to maintain the integrity of the image." I downloaded the latest version of Topaz AI and gave it a whirl. To sum it up, Topaz DeNoise is an intuitive and easy to understand plugin that aims to provide users with the ability to reduce the level of noise in their digital photos, while also trying to maintain details in an acceptable range.Kevin, thanks for posting this information. When complete, users can press the ‘OK’ button and the picture will be processed in just a few moments. The ‘Debanding’ component allows them to set the ‘Banding Width’, applying it horizontally or vertically. Similarly, the ‘Detail Recovery’ function lets users decide how much to ‘Recover Detail’, ‘Reduce Blur’ or ‘Add Grain’. The ‘Noise Reduction’ tool enables users to modify the ‘Overall Strength’, ‘Adjust Shadow’, ‘Adjust Highlight’, ‘Adjust Color’ or ‘Correct Black Level’. The ‘Sample Presets’ include several JPEG and RAW degrees of noise reduction, which can be applied onto the photo, letting them switch between ‘Original’ and ‘Processed’ with a simple button press, in order to analyze the alterations. The plugin allows users to open the picture they wish to process in the main window, while the left and right side panels enable them to select the preferred preset, or manually adjust the ‘Noise Reduction’, ‘Detail Recovery’ and ‘Debanding’. Denoising images with custom-built or preset values When complete, users can begin to work with Topaz DeNoise right away, as it does not require much experience in order to handle it properly, particularly if they managed to get passed installation, which is not precisely for beginners. However, the help documentation provides step by step instructions for many of the aforementioned tools. The utility features an executable installer, but depending on the host software, its installation may also require additional stepsvary. Topaz DeNoise is a useful and efficient piece of software functioning as a plugin for a variety of image editing software, the most popular of which are Photoshop CC, Lightroom, Irfanview, Iphoto, Aperture, Corel PaintShop and several others.
