These are side-by-side comparison photographs; the (mostly) non-edited examples are on the left. Please note the composition may look different due to digital cropping but the edited examples are born from the same file(s).
In the edited photograph above, the tiling, bath tub, bath panel, shadows, reflections, metals, glass, etc. have been edited to look cleaner/brighter. Some objects have been removed/shaped differently. Artificial light was added to simulate sunlight.
In the edited photograph above, artificial light was primarily used to correct colour casts -- not to illuminate the scene. Local contrast/colour adjustments have been made throughout the scene, and a few minor adjustments have been made to objects e.g. the cupboards.
In the edited photograph above, the silicone sealant around the bidet has been completely edited, and I applied local colour adjustments to make the image look more-pleasing; the original photograph on the left is closer to a natural look. The original was taken with mostly simulated light due to such a small natural light-source. A digital tilt-shift effect has been added to both photographs to make comparisons easier.
