DxO ViewPoint 5.15.0 — Mac version

The standalone app processes 8-bit and 16-bit TIFF files up to 200 MB. That limit matters if you stitch panoramas or scan medium-format film, because the file sizes climb quickly. Stick within it and the software handles the rest without breaking a sweat.

On the Mac, you need macOS 11 (Big Sur) or later, and the app runs natively on both Intel and Apple Silicon machines. It works as a standalone tool for TIFFs, or you can slot it in as a plug-in inside Adobe Photoshop and Lightroom Classic. That flexibility means you can fix a tilted horizon in a landscape or pull back stretched-out shapes at the edges of a wide-angle shot without leaving your usual editing flow.

The tools are precise. Volume Deformation sorts out proportion problems that make people look squashed near the frame edge. ReShape Fusion lets you move, scale, and rotate any part of an image independently. You can straighten a crooked horizon in one click, or dig into the advanced controls to tweak converging verticals on a building until they sit dead straight.

It's a focused toolkit, not an all-in-one editor. If your workflow already lives inside Lightroom or Photoshop, the plug-in route keeps everything tidy. If you prefer working on a flat TIFF outside a host, the standalone app gets the job done on any supported Mac.

Straightening a church interior from TIFF

Say you shot a church interior with a 16mm lens. The pews lean inwards, the altar looks pinched, and the floor slopes off to one side. You drag the TIFF into the standalone app.

First, you hit the horizon tool. A line appears across the image. You drag it to match the altar step and the whole room levels out. Next, you open the perspective panel and draw two vertical guides along the pillars. The software pulls them parallel. The roof vaults suddenly look right.

Now you zoom in on the pew ends. The people sitting there have stretched heads. You switch to Volume Deformation and paint a rough mask over the affected area. A slider brings their proportions back to normal without touching the rest of the frame. You save a 16-bit TIFF and drop it into Lightroom for final colour work. The whole fix took under four minutes.

Why short perspective guides wobble when you zoom in

The most common slip is drawing perspective guides too short. A tiny line along a window frame will give you a correction that looks fine at thumbnail size but wobbles when you zoom in. Drag your guides right across the image, edge to edge, using the longest straight element you can find.

Another is over-correcting converging verticals on tall buildings. A slight taper looks natural to the eye. Pulling every line dead parallel can make the top of a tower look wider than the base. Back off the slider until the building feels solid, not sterile.

People also miss the crop preview. After a heavy perspective shift, the usable image area shrinks. Toggle the crop overlay before you export, or you'll end up with transparent corners in your TIFF. The standalone app won't auto-crop unless you tell it to.

Finally, if you searched intitle:"dxo viewpoint" "free download" and landed here with a batch of raw files, remember the standalone app works with TIFFs and JPEGs. For raw processing, you'll want the plug-in route inside Lightroom or Photoshop. Dragging a .CR3 straight into the app won't work.
