I realize I've been away from this forum for some time. That's because I've just been extremely busy running a film processing lab, and developing my scanning software Simple Image Tools into something that I can make available for others to use.

With that being said, I'm looking to see what cameras and hardware/OS/Platform most people use so I can target an initial audience for beta testing and support to get the widest spread. If this is something you might want to participate in, just respond here with what you use.

What is Simple Image Tools? It's an in-house digital camera film scanning software application written by me for use in my film processing lab. I've been using it almost exclusively since roughly 2018-2019 time frame and have been eating my own dog food and improving it this whole time. It's been through many revisions in that time period, and many of you used my services and have seen scans from it for a while, though if you've not sent film in for processing recently, then you've only seen early outputs. It's done nothing but get better since.

At any rate, I've had multiple people here (and elsewhere) express an interest in having this tool available for their own use. I'm not against this, as long as I can support it, but... this tool was originally written to work in a high volume lab environment and does not have a very user friendly interface, and in many respects, was missing major pieces of UI functionality in favor of configuration files and was originally designed to generate DNG files and be used primarily alongside Adobe's software suite.

Well, that was then. Now:

1. Uses libraw and natively supports most cameras libraw supports, though in the interest keeping things sane for me, I will have a supported cameras list. Technically, it can do it, but it does actually have to do it acceptably, so needs to be officially supported by me.
2. Outputs generic baseline tiff files with embedded ICC profile that can be used with anything that supports tiff files, so no reliance on Adobe products.
3. Runs as a standalone (with a much nicer looking) GUI application that does everything internally, so no reliance on any third party paid software. Uses Libraw, libtiff, littlecms internally.
4. Planned support for different scanning profiles for those that want to do their own custom profiles, though the current baseline c-41 is pretty good, can do C-41, E-6, and BW.
5. It's a full on multithreaded monster that will use as many cores as you can throw at it. More processing cores means it processes the frames in a roll faster. You're only limited by processing cores, ram, and how fast your storage is.
6. Implemented using as much generic code as possible with plans to support multiple platforms.

Point 6 is where you guys and gals come in. I personally use x86-64 on FreeBSD and MacOS (with no plans to change that any time soon), but I also fully recognize that other people use other stuff.... So... what is this other stuff you guys/gals use?

I'm still probably 3-6 months away from having something ready that can be tested by the general public, but I'm close enough that I want to focus efforts on what most people that would be interested in this are using.

So let's have at it. List your stuff out.

MacOS on the max-config Macbook Pro with an external Apple Studio display. My biggest concern looking at your list is applying the lens profile which Adobe does automatically. The Sigma macros, while the sharpest, are a bit bubbly.

Give it to me. I am not general public. I'll fix the bugs myself if needed :smile:

How do you know what you're seeing isn't from the lens on the film camera that was used to take the original photo? Or a combination of that lens plus whatever lens you're using on your scanning rig? Or a combination of that plus the film wasn't flat? So do you want to remove lens problems from the scanning rig plus the lens from the film camera? Or just the scanning rig? How about keep it simple and do neither?

That being said... lens profiles are a bit of a sticky subject. I'd like to avoid being in the business of supporting whatever somebodies favorite lens is for no other reason than it's their favorite lens. Kind of the same boat as supporting cameras for no reason other than somebody thinks it's the best camera ever. If there's a clear winner that most people use, that'll go on the list of things to support, otherwise... maybe if enough people use it...

Well, that is the most simple decision. In scanning you only employ corrections for the scanning lens.

Thanks, very interesting!
Usage without any Adobe products sounds very good!

My hardware / software equipment:
intel Core i3-7130U (2.7 GHz, 3MB L3 cache) ; 8 GB DDR4 Memory ; 1000 GB HD ;
and Windows 10.

Having seen the results from earlier versions of your Simple Image Tools software, I am looking forward to seeing the finished product.

I am running MacOS 13.6.7 Ventura on a 2020 Intel iMac (iMac20,1). I usually lag about one version behind the latest version of the Mac OS software, so it will be time for me to update to Sonoma soon. I tend to keep my hardware much longer, 5-10 years, but obviously my next Mac will have some variation of their M-series chip rather than Intel.

My scanning camera is presently an old Fuji X-T1. If I decide to upgrade my digital camera, I will probably stick with Fuji, but I can't afford their latest models. Hopefully your RAW converter will be able to do a good job with files from a Fuji X-Trans sensor; if not, that might be a problem for me.

My scanning camera is an Olympus OM-D EM1 mk ii. I tether it to the computer for convenience and run the Olympus software, which means I have to run Windows. I convert the scans in Affinity photo.

I also dual boot into Linux, so for the sake of testing software I can easily skip the tethering and transfer files from the memory card to do the conversion in Linux instead.

As for computer specs… can’t really remember… An AMD Ryzen 5 something or other, 24 Gb RAM, and an Nvidia Gforce 1080.

Pentax K-1 with 50mm f/2.8 macro lens and pixel shift, CS-Lite light source, essential film holder or anti-newton glass sandwich with DIY light masks, small rig parts for copystand setup.

Camera is untethered and I transfer to desktop computer by inserting the memory card, computer runs Windows 10 and has 32GB of ram, processor was top of the line about 5 years ago, with a decent video card capable of supporting 4K resolution on a 65 inch TV display.

I currently use RawTherapee to convert to tif and Gimp for editing.

Libraw technically supports xtrans, but unless a whole pile of people use that sensor type it will be some time before I officially support it in simple image tools. It is quite literally the definition of special handling, and because it has significantly reduced color resolution, I don’t recommend it for c-41 scanning.

I guess you can cross me off of your list, then. I think I've been getting OK results using Negative Lab Pro to convert photos of C-41 negatives taken with my Fuji camera, but that is based only a few rolls of film, and I've not tried any other camera for comparison.

I could pick up a non-Fuji camera just for camera scanning. My old Fuji is only 16MP, so I might benefit from more pixels when digitizing film. Do you have any preference for working with Nikon files vs. Canon, vs. whatever? I prefer mirrorless, but my only real requirement for scanning would be an adaptor to fit the camera to the Pentax screw mount bellows I use with my copy lens.

Because both lenses, the image-taking one and the digitizing one, are both regularly used on digital bodies and I'm aware of their native characteristics. The digitizing Sigma has visible pincushion distortion, and if you digitize a negative taken with the same lens on film, it gets amplified to a degree that you can't have any trees or buildings in a scene.

With Bayer CFA sensors, it doesn't matter much, though I use Canon in-house. My hardware evolution was a Rebel T3i, then a Canon 80D, then a 90D, then the R5. I've been toying with getting a Fuji medium format system for scanning medium format film, but only so that I can get better than the roughly 2400 dpi I can muster with the current system.

I don't know about an adapter for your particular setup, but you should be able to pick up a used EF-m or RF crop body that's 20+ MP for relatively cheap. The R7 is a close cousin to the 90D, it just has a different micro-lens array over the sensor to account for the fact that the back of the lens mounted on the body is a lot closer than on an EF-s mount camera. The M50 is a close cousin to the 80D. If you prefer full frame bodies, the R8 is a good starting point.

That said, I'm not against x-trans sensors per se, they just come with a bunch of technicalities that are less than ideal for scanning film. If enough people have them and want to use them it'll be supported. It's just a matter of whether the amount of work required to properly support it would actually result in enough people buying a license to pay for the work.

I use Macs and copy images from the camera's memory card to the computer, catalog with Lightroom and use either Lightroom or Photoshop for whatever editing I do.

I use an Olympus OM-D E-M1 mark iii and Zuiko 60mm Macro (with Valoi advancer holders) for my camera scanning. All PP done on an M1 MacBook Pro using Capture One, with occasional forays into Affinity Photo. I haven't used a Windows PC for years.

Would importing a raw tiff scan from Vuescan work as well? I am using an old Minolta Elite Scan II for 35mm and Epson V800 for medium format.

Super old laptop, mostly Kubuntu (mostly the latest release), but have Win10 floating around as well. For the moment I am using Darktable negadoctor for inversion...

For a camera, a Fuji XT5 with 60mm Macro lens. For computer, MacBook Air with the M1 chip. I've been doing C41 and B/W with it. Currently using FilmLab for the C41 conversion but if there is something better I'm all ears, as I'm not entirely happy with it, and I don't want to pay for another SilverFast license to put that on my laptop just so I can process color negatives.

Another Fuji user here. I scan my B&W negatives with an X-T20 and process the files with Affinity Photo on an M1 MacBook Air. I do not shoot color film so color processing is not an issue.

@Adrian Bacon, While I briefly considered getting a non-Fuji digital camera which I could dedicate to film scanning, I soon abandoned that idea for a number of reasons. And after looking at the competition, when I finally decide to replace my old Fuji X-T1, I'm pretty sure I will get a Fuji X-T5.

So the bottom line for me is:
IF your software can give good results when inverting RAW color negative files made with a Fuji X-Trans sensor, and
IF I like your GUI, and
IF it will run on my Mac computer, and
IF I can purchase your sofware for less than $200,
... then then it is quite likely I will be a customer for you.

Otherwise, I will probably continue to use Negative Lab Pro with Adobe Lightroom.

About the GUI, there is one feature I really depend on when using any photo editing software, and that is the ability to instantly Undo and Redo any adjustment. Preferably with keyboard shortcuts. If it takes any significant amount of time to redraw the screen when I Undo / Redo the edit, then it becomes too difficult for me evaluate the success of the edit.

Thanks for listening.

I copy the RAW and JPEG files to a memory stick and to my PC laptop. Later the files are copied to my Mac tower. No post processing is done on the Mac since it is too out of date, but that will change when I replace the Mac Pro Tower with a new model. I only work with the RAW files using Abode LightRoom and then Adobe PhotoShop Classic. No files are ever uploaded or even allowed on the Cloud in any form. JPEG files go along for the ride and are backed up, but I do not use them.

If libraw can load read it and load the raw samples into ram, technically, yes, though I'd have to write code to handle that particular pixel layout (i.e. what order the RGB samples are, whether their big endian or little endian, etc). If the raw output from Vuescan is saved as a DNG, that makes life a lot easier, but would still require explicit support.

I'm puzzled by all the people using Fuji cameras with Xtrans sensors to scan their precious film.

One of the reasons why I entirely left digital cameras behind years ago and went back to film cameras and a dedicated film scanner was how poor my Fuji XT-20 Xtrans sensor was at rendering fine detail.

The in camera jpegs (which were wonderful with my Nikon DSLRs) were pathetic with the Fuji. Many people reported the same issue with demosaicised Fuji output, and the phenomenon was often described as "Fuji worms" or "Fuji painterly effect". At the time the only tools able to somewhat ameliorate the worms issues were expensive third party tools. Adobe raw made a mess out of them, worse worms that the in camera jpegs.

Perhaps Fuji has fixed this later on, but personally I would never put an Xtrans sensor of that generation close to my negatives.
