![]() ![]() This is why they often look different depending on the program used to open them, and effectively they are different if your software treats them differently. For example tiff is assumed to have a gamma of 0.454545 as there is no mechanism to say otherwise where as DNG does have such a mechanism. The data is identical they are both linear, and no color matrix has been applied, it just the way different programs interpret the meta data or make assumptions. Let us know how the dng file to tiff works or if you just use the dng file.That's excellent if that is the case, problem solved. At least that is the way I understand it. Ie, the file is not a linear file anymore which is what the raw file is, no type of processing in the least. Yes, the data is identical except all the Vuescan conversions and such are there as well. Ever since Adobe released Lightroom 6 and CC, the capability to stitch images into DNG files has been integrated right into the product core. I believe it since my 4000 dpi scan gives me 1.75 GB. I might still have it in my trash bin on my mac that I can check out this weekend to double check, but I am pretty sure. Going above that will start generating files that could exceed the 4GB limitation, which would defeat my purposes as I use the raw files for post-processing. Want to rescan the one file at 2400 dpi with no AA, but do not think it can make up the difference as it really is night and day. I also turned off the anti-aliasing feature. That file is approximately 1.8 or so GB in size. Just made the comparisons from scans I did yesterday. I use the better scanning setup for wet scan with Kami fluid. Anyway, if you can convert it back after you save (since it is a tif dng file) you could then create files bigger than 4gb.Īs a side note fwiw, I use an epson v850 and the difference in scanning 4x5 at 2400 dpi and 4000 dpi is night and day. Learn more about DNG files What is a RAW file RAW files are just that raw, untouched, and unprocessed images recorded directly from a camera’s sensor. ![]() I was reading on one site, I believe Colorfast who does the color raw and color neg plug in for ps, that you can take the dng created by vue scan and then convert it back to tif so that you can get the linear information. DNG is an open-source, royalty-free, highly compatible, and continuously improving raw image format that was built for editing photos especially with Adobe software. What is the max size of camera raw in ps? I wonder since I created the file and saved it, if you could then use a program to convert the dng file back to tif. PTGui belongs to the category of in-depth panorama stitching programs that offer a huge library of features, complex projections (the way your set of images are actually mapped), and powerful. So I made a scan that was like 5.5 GB and saved it as a dng file with vue scan (not a raw) I tried to open it in ps, but ps couldn't read it. ![]()
