FastRawViewer

Fastest gun in the West. You don't have to You also don't have to use RAW if you have a high resolution camera like the Nikon D850, Sony A7R II or A7R III or the Canon 5DS R. Embedded previews or accompanying jpegs work great and even faster. I use FastRawViewer to offload files from SD and CompactFlash Media, to throw away dud photos and rate the rest. Then I take the keepers put them in another folder and process them in DxO Photo Lab or Iridient Developer. There's no faster workflow for dealing with an event and getting to high quality jpegs from original RAW. If you are a photographer, FastRawViewer is the best $15 (or $20) you will ever spend on software. As other users have pointed out, FastRawViewer is kept up to date. Aesthetically FastRawViewer (a cross-platform app) is not the prettiest app in Mac history. it's easy to go to remove all the ugly chrome though just by pressing tab just like in Photoshop. FastRawViewer is infinitely configurable in what it will display (depending on your monitor size and needs) so the user can improve its looks considerably with just a little effort.

If you need to examine a lot of raws very quickly, this application is blazingly fast and well priced with regular updates and very good support. Even using a Lightroom workflow, it's too slow when having to 'pre-edit' thousands of shots, this app can do so much faster prior to import into a catalog system. It's agonizing to go back to LR's Library mode which is so utterly slow and why this product is what the LR library experience SHOULD be like but probably never will be. Plus a raw Histogram! A must have just for that functionality alone!

Absolutely recommended. I shoot RAW, so this app lets me see the original file as it is and not only the JPEG version (which I can see if I wish to)
FastRawViewer is now part of my workflow (I suppose it could be improved) : I move my RAW files from my card to a folder on my desktop, open the folder in FRV, move the rejected files to the autogenerated folder, put that folder to the crash, move the folder with the selected pictures on my Pictures folder on my external HD and import in my DAM app.
The app is fast, steadily upgraded and I think (not sure about this one) it's the only one that allows to view the RAW file and not the embedded JPEG.
I do real estate bracketed shooting and I have to deliver my work quickly. FRW saves me a huge amount of time (and of money compared to the excellent PhotoMechanic)

I just discovered this app today. I was looking at renewing my license for Photo Mechanic and found this app mentioned by others. No, it is not as complete and as robust as Photo Mechanic, nor is it anywhere near as expensive. For my purposes, this app does what I need and it works great. I am using it to organize my huge collection of JPEG files. I don't shoot RAW - yet. This app opens folders with lots of files quickly and it also scrolls very quickly. As I am a highly visually oriented user, this is a plus, to see what I have as fast as I can scroll. It allows me to link to three different external apps to edit with just as Photo Mechanic did. I have not played with what tweaks I can make directly in this app yet. There appear to be some but I am more interested in using it to catalog my images and to use external apps for the edits. I have taken some time away from photography so most of what I have is out of date. I don't yet know which app I will choose going forward. Some have already built-in DAM features and some don’t. But for $20 and this much functionality, I am very happy to have found it. I don't even know which camera I will use but I am imagining a Fuji XT-2 is in my future. I know Fuji RAW files are a bit different so I don't know how well it will work with RAW files, Fuji or otherwise - but I am not buying this app for that purpose - yet. There are one or two missing pieces which I am not taking away a star from as the developer responded that they will be added in upcoming versions and named the versions. I have also seen this mentioned in their site blog so I am trusting them to follow up for the time being. Current version as of this review is 1.3.8. According to the developers feedback; Display of File Modify Date in EXIF pane will be in 1.3.9 (very soon) Sorting by size will included with version 1.4 Handling TIFF files will be available in 1.5 I am already impressed that this app seems stable, seems more than capable for what I need it for, and that the developer has responded quickly and professionally to my pre-sales questions. And the price, yep, that about does it for me, Five stars.
