Reviews of topaz dejpeg5/1/2023 ![]() Remember that this is not an alternative to shooting in raw. But what Topaz has managed to do here with their JPEG to RAW AI software is truly praiseworthy. Technically it is impossible to get a raw file out of a JPEG. This is to say that the output file actually had a greater dynamic range that I could play around with. The extent to which I could recover shadow and highlight details was definitely greater in the DNG file. Working with the DNG image felt like working with an actual raw file from a camera. ![]() Once I was done playing around and trying to push the software to its limits, I tried out some serious editing and was again awestruck. Artifacts are minimal and the details are well preserved. Although I pushed the software a bit hard, the result was very much impressive. Whereas, when I applied the same exposure settings on the DNG file, it held up quite well. There were visible grey patches in the shadow regions and everything appeared blotchy. Here’s how the original JPEG file broke into pieces. I did the same thing with both the original JPEG file and the exported DNG file, and the difference was pretty obvious. Here, the real surprise kicked in when I pushed the exposure and raised the shadows up to the extreme. That’s the software’s AI building on the details that were already there on the original JPEG.Īfter some simple adjustments to reduce blur and jpeg artifacts, I exported the file in DNG format and opened it up with Camera Raw. I knew this would be an extreme test for the software but I really wanted to see how much I could push it.Īt first, what impressed me was the fact that the raw preview actually came out more detailed and sharper than the JPEG input. I was really excited to try out this software so I opened up a high-contrast black and white image with crushed blacks. You can either choose to save the output raw file in DNG, TIF, or TIFF formats as per your preference. I wish there was a dedicated button to refresh the preview once I was done making the adjustments.Īnother set of options that you’ll see in the software is to set the file extension. That slowed the process down to some extent. One thing I didn’t like was how the preview refreshed every time I made any adjustments. If you want, you can even leave it to auto and let the software run its magic. You just get the option to adjust the amount by which you want to reduce JPEG artifacts and to remove blur. Even the controls that you’ll see for image processing are minimal but it gets the job done. It’s to the point without much of a fuss. ![]() Like with any other software from Topaz Labs, the interface is very simple and user-friendly. Once the software is up and ready, you have the option to either work with a single image or with a batch to save time. You have to launch it as you would launch any other software. Sounds really impressive right? How to Convert JPEG to RAWīeing a standalone software, you cannot launch Topaz JPG to RAW AI from another software like Lightroom or Photoshop, as a plugin. This way, the neural network remembers the correspondence and will output higher quality images even when given a new JPEG image as an input. According to Topaz, that’s because they’ve trained their neural network on a large number of high-quality raw images with their corresponding JPEG version. It really feels like working with an original raw file. ![]() Working with the software is so seamless and it is really amazing how it manages to preserve the details. What I was most impressed with when working with Topaz JPEG to RAW AI was the mere absence of any sort of artifacts. This ensures that no banding occurs when you’re processing the file. Actually, it expands the bit depth from an 8-bit sRGB color profile in the JPEG to a 16-bit ProPhoto RGB color profile in the final raw file. The software also analyzes the existing colors in the JPEG files and adds more color information. Because of this, I noticed that I was able to recover a greater amount of shadow and highlight details. Topaz JPEG to RAW AI can analyze the JPEG file that has been fed to it and create an output that has a greater dynamic range than the original file. Raw files, on the other hand, can capture about 15 stops depending on the sensor type. JPEG files typically can capture about 8 stops of dynamic range.
