Description Pixelmator Photo is the most powerful photo editing app ever designed for a mobile device. Ratings and Reviews. Yearly Subscription. Unlimited Access. App Privacy. Size As for noise reduction, we have ML Denoise in Pixelmator Pro on Mac so it's something we would like to bring to iPad, although it's not quite as simple as it might seem.
Can not find it via google. Tue Apr 14, pm I would also like to see a noise reduction option. I have assumed a workflow that starts with raw image files from the camera, not JPGs, for high-quality results. And I have assumed the goal of making that raw image look as good as possible at the raw stage, before it goes to Photoshop or some other bit-mapped editor.
However, I made no attempt to evaluate all these programs for a wide range of photo applications. That would be a monumental task! Nor, in the few programs capable of the task, did I test image layering. My focus was on developing a raw image. GIMP users must turn to one of the raw developers here as a first stage.
If you are curious how a program might perform for your purposes and on your photos, then why not test drive a trial copy? None of the programs I tested ticked all the boxes in providing all the functions and image quality of the Adobe products.
None of the non-Adobe programs will work with the third-party software LRTimelapse www. It is an essential tool for advanced time-lapse processing. If serious and professional time-lapse shooting is your goal, none of the Adobe contenders will work.
Subscribe to Creative Cloud. And buy LRTimelapse. However, for less-demanding time-lapse shooting, when the same settings can be applied to all the images in a sequence, then I feel the best non-Adobe choices are, in alphabetical order:.
Scroll to the end for more details and a link. If you are processing just individual still images, perhaps needing only to stack or composite a few exposures, and want to do all the raw development and subsequent layering of images within one non-Adobe program, then look at again alphabetically :. Luminar has better noise reduction but it demands more manual work to stack and blend images. While ON1 Photo Raw has some fine features and good masking tools, it exhibits odd de-Bayering artifacts, giving images a cross-hatched appearance at the pixel-peeping level.
Absolutely essential is effective noise reduction, of luminance noise and chrominance color speckles and splotches. I judged other programs on their ability to produce results as good as this, if not better, using their noise reduction sliders.
Some programs did better than others in providing smooth, noiseless skies and ground, while retaining detail. For example, one of the best was DxO PhotoLab, above. It has excellent options for reducing noise without being overwhelming in its choices, the case with a couple of other programs. I describe its other deficiencies below. The wide-angle lenses we typically use in nightscape and time-lapse imaging suffer from vignetting and lens distortions.
Having software that can automatically detect the lens used and apply bespoke corrections is wonderful. Only a few programs, such as Capture One above , have a library of camera and lens data to draw upon to apply accurate corrections with one click. With others you have to dial in corrections manually by eye, which is crude and inaccurate. All programs have exposure and contrast adjustments, but the key to making a Milky Way nightscape look good is being able to boost the shadows the dark ground while preventing the sky from becoming overly bright, yet while still applying good contrast to the sky.
With most other programs it was tough to boost the shadows without also flattening the contrast. However, any local adjustments like those will be feasible only for still images or time-lapses where the camera does not move.
In any motion control sequences the horizon will be shifting from frame to frame, making precise masking impractical over a sequence of hundreds of images. But they are nice to have. Some programs have an HSL panel Hue, Saturation, Lightness or an equalizer-style control for boosting or dialing back specific colors.
Capture One above has the most control over color correction, with an impressive array of color wheels and sliders that can be set to tweak a broad or narrow range of colors. And yet, despite this, I was still unable to make my test image look quite the way I wanted for color balance.
Even when shooting nightscape stills we often take several images to stack later. And then to be able to inspect those images in thumbnails to be sure they all look good. Some programs Affinity Photo, Luminar, Pixelmator Pro lack any library function for viewing or browsing a folder of thumbnail images. This is absolutely essential for time-lapse work, and nice to have even when working on a small set to be stacked into a still image.
This step is to create an intermediate set of JPGs to assemble into a movie. Or perhaps to stack into a star trail composite using third party software such as StarStaX , or to work on the images in another layer-based program of your choice.
As ON1 Photo RAW shows above, this is best done using a Library or Browser mode to visually select the images, then call up an Export panel or menu to choose the image size, format, quality, and location for the exports. Click Export and go for coffee — or a leisurely dinner — while the program works through your folder. All programs took an hour or more to export hundreds of images. Those functions were the key features I looked for when evaluating the programs for nightscape and time-lapse work.
Every program had other attractive features, often ones I wished were in Adobe Camera Raw. But if the program lacked any of the above features, I judged it unsuitable. Yes, the new contenders to the Photoshop crown have the benefit of starting from a blank slate for interface design.
Many, such as Luminar above, have a clean, attractive design, with less reliance on menus than Photoshop. Photoshop has grown haphazardly over 25 years, resulting in complex menus. Just finding key functions can take many tutorial courses! It can copy and paste settings and batch export images, for time-lapses. It is certainly affordable, making it a low-cost Lightroom contender.
CONS: It lacks any gradient or local adjustments, or even spot removal brushes. Lens corrections are just manual. There is no dehaze control, which can be useful for snapping up even clear night skies. You cannot layer images to create composites or image stacks. This is not a Photoshop replacement. It has a command for image stacking with a choice of stack modes for averaging and adding images. It works fine when restricted to working on just a handful of images.
Pixelmator Pro 1. In this update to it a version 2. Removing compression blocks in heavily compressed images. Improving how portrait photos are upscaled. Preserving sharp edges and details in illustrations. Making the new, smarter algorithm faster and more efficient. The previous algorithm already did a great job at removing the small compression artifacts Compression Artifacts Compression artifacts often look like small dots and appear at edge areas — where contrasting colors meet in images.
But JPEGs, especially ones that have been compressed quite a lot, will also feature visible compression blocks Compression Blocks JPEG compression blocks appear when the compression algorithm reduces subtly differently colored pixels for example, in gradients to one color. This new version of ML Super Resolution does an even better job with the small artifacts and it takes care of the blocks! Download Image. We had actually been working on this since before the original release and wanted to include it when ML Super Resolution first came out.
After some digging, it became clear that certain sizes of text in our training dataset were being interpreted as compression blocks!
