But, going forward, I’ll break out Pixelmator Pro if I need a high-quality image enlargement or reduction. I’m still a fan of Affinity Photos, and I still use it for most of my image editing. I urge you to visit the Pixelmator blog (, where you can read about the technology behind ML Super Resolution and see examples compared to the three most common algorithms-Bilinear, Nearest Neighbor, and Lanczos. And, while machine learning requires more processing power than other algorithms-between 8,000 and 62,000 times more according to Pixelmator-images were processed in just a few seconds each on my 2015 MacBook Pro. Here’s an example: Left to right: Original Nearest Neighbor Bilinear Lanczos ML Super Resolution.īehind the scenes, the magic is done by machine learning, which attempts to recognize edges, patterns, and textures, and then recreate detail based on its dataset and extensive training. Sometimes the improvements are modest other times the improvements are striking but, in every case, ML Super Resolution looked better to my eye. I tried it with half a dozen different images, and it does a better job of enlarging (and reducing) the dimensions and resolution of photos than other available algorithms. While it can’t enlarge a postage-stamp sized low-resolution image to a perfect poster-sized high-res image, I’m amazed at how well the machine learning algorithm works to double, triple, or even quadruple the size and resolution of many images. I’m not sure I’d go that far, but after a couple of days of testing, I’m quite impressed. The blog post announcing the new feature proudly proclaimed, “Yes, zooming and enhancing images like they do in all those cheesy police dramas is now a reality!” Last week, however, Pixelmator Pro introduced a breakthrough feature called ML Super Resolution that uses machine learning to increase the resolution (size) of an image without losing (much) detail or introducing unwanted artifacts. If you try to enlarge or reduce most images using those algorithms, the result will look better than if no algorithm were applied, but will rarely look great. Over the years graphics apps have improved at scaling images using algorithms with names like Bilinear and Nearest Neighbor, but the results have never been great. If you’ve been manipulating images with a computer as long as I have, you know that the holy grail for image-processing apps like Photoshop, Affinity Photo, and Pixelmator Pro is to enlarge (or reduce) an image without introducing visible artifacts, blurriness, jagged edges, or other unwanted elements. Zoom in to get a better look at the details if required.Any sufficiently advanced technology is indistinguishable from magic. Now, place the brush over the object that needs to be removed and click on it a few times or drag the brush over it to remove the object and blend it into the background. It's important to use the right size brush for this. Tap on ' Size' to adjust the size of the brush using the slider tool. In the sidebar on the right, scroll down to the ' Retouch' option. In the Photos app on Mac, select the photo that needs to be edited, and then click on the ' Edit' button in the top-right corner. Alternatively, iPhone users can AirDrop a photo to Mac and then open it in Photos. The easiest way is by using iCloud, which will automatically sync images to the Photos app on a Mac. To edit an iPhone photo on Mac, users will first need to transfer it. The Mac Photos app has the quick one-touch editing tools available on iPhone, but users can also go deeper to adjust different parameters. ![]() Although Photos is available on both iPhone and Mac, the editing tools are far superior on a Mac computer. While not all iPhone users may own a Mac computer, for those that do, there's a way to erase objects for free using the Photos app. To share the photo, tap the share button (box with upwards arrow) and then ' Share to' to share it in an app of choice. To go back to the original image, tap ' Reset,' or to save the edited image, tap ' Done.' Tap ' Save Copy' to save a copy of the edited image to Google Photos. It might take a few tries to get the perfect result. Magic Eraser will automatically remove the object and blend the area into the background. If no suggestions are provided, make sure ' Erase' is selected on the screen, and then highlight the object that needs to be removed by drawing a circle around it. Next, tap the edit button (three horizontal lines) at the bottom and tap ' Tools.' Tap ' Magic Eraser,' wait for the app to provide suggestions, and tap ' Erase.' Once the relevant photos are backed up, open the Google Photos app on iPhone and select a photo to edit. It's worth noting that users can also manually upload photos to Google Photos from a PC by opening the Google Photos website on their browser, signing in, and then tapping ' Upload' at the top.
