You can see this most easily in the really fine feathers beneath and immediately behind the eye. Switching to HQ denoising improves both of these defects considerably, but it definitely discards a good bit of fine detail too, throwing the baby out with the bathwater. False color also intrudes, especially in the reflective water droplets and the fine folds of the duck's lower eyelid. Again, we can see quite a bit of noise prior to denoising, especially noticeable in the duck's eye. Increasing the sensitivity a little to ISO 3200 with a shot from our Fujifilm X-S10 review, we have a tightly-cropped shot of a duck's head with the feathers freshy wetted from a visit beneath the water. Its result is even crisper, and it restores more of the fine details, yielding a less plasticky feel than the standard DeepPRIME. The base HQ denoising algorithm cleans things up considerably, but it also robs some detail from the finer flour particles stuck to the bread, and the cracking in the crust looks a bit soft at 1:1 resolution.Īnd while DeepPRIME crispens things up, the newly-available DeepPRIME XD algorithm definitely does a much better job. As you can see, with no denoising applied the noise intrudes quite a bit and, despite the X-Trans color filter array, there's still a fair bit of false color artifacting on display too. We'll start off with a shot from our Fujifilm X-T4 review at ISO 2500, a moderately high sensitivity. So how does DeepPRIME get on with X-Trans imagery in the real world? Let's roll up our sleeves and take a closer look, courtesy of a selection of high ISO shots from our recent Fujifilm X-series reviews!Īll sample images and their crops in this article were converted from raw using the just-released PhotoLab 6.5 update (also available for macOS) with its "DxO Optical Corrections only" preset, and each denoising algorithm was used at its default settings. (This leaves just the company's standard PRIME denoising algorithm and a handful of more minor features off the table for your X-series camera.) The recent arrival of PhotoLab 6.4 has now closed the biggest of these, bringing support for the company's top-of-the-line DeepPRIME and DeepPRIME XD denoising algorithms to Fujifilm X-series shooters. That brought basic X-Trans support, although a couple of gaps remained in which noise reduction algorithms were available for it. In October 2021, that finally started to change with the introduction of DxO's PhotoLab 5. You can click each crop in the rollover galleries below to open the full-sized, DxO-processed JPEG.
