I'm going to have to search for a batch way to convert my black and white images to 24 or 48 bits per pixel. later, that didn't work, I'll try a straight link Not really sure how to include an image here, but I hope this should lead to a screen grab of the preview with the little cross I mentioned. The "SRB color space" should have been sRGB, sorry about that one! I guess I didn't really understand your earlier remark about grey images, as it was so far outside my concept of a modern image processing engine! But I'm gradually getting there. I use Silverfast Plus SE for my color, B&W and inversible color films, and I don't face any issue. I think you could have a mess with color spaces and profiles, which could come from your scanning software. Now compare the file sizes of the 6 images. Download CONTENTA CONVERTER Premium Convert DNG photos Quick and easy v6.71 The most intuitive software to transform your photos Select photos Configure Convert Prepare for web, print, backup. The file format conversion API also supports rendering remote documents from different sources including S3, Blob, FTP, Stream, URL or a local disk. Everything in one go and in just a few easy steps. Convert Password Protected DNG to TIFF Accurately load and convert documents that are protected with a password within your Java based applications. Convert the Original TIFF to DNG, Uncheck all three Checkboxes, JPEG Preview Medium. Answer You can use our software Contenta Converter PREMIUM to convert thousands of DNG to TIFF. Choose the file type as DNG, Uncheck all three Checkboxes, JPEG Preview Medium. Photoshop and its variants also use ACR, but TIFF conversion is built in (they can save in TIF/TIFF) without going via ACR. It uses Adobe Camera RAW which is set up for RAW files and TIFF isn't a RAW format. I had to go to Photoshop and transform the color mode from grey to RGB, one by one, and it worked then. Choose the file type as TIFF, Compression equals ZIP, Bit Depth equal 8. It isn't surprising that DNG Converter can't open TIFF files. I had a similar issue with some old black and white negatives I scanned a long time ago, unfortunately using a grey color space : Capture One succeeded in importing these images, but couldn't edit them. They too did not transfer!Ĭould you please show this "grey and orange cross in the corner of the preview" you mention in your last message ?Īnd what is this "SRB color space" ? Anyway, all the pictures with a grey color space are not editable by Capture One. I suspect not!) It is also noticeable that some images in that Project were also scanned with a trial version of Silverfast Plus SE on the same scanner. (I'm not sure if it's significant that the editable ones had filenames xxxx.tiff whereas the uneditable ones had filenames xxyy.tif. Aperture thinks these have a color profile of Adobe RGB, whereas C1Pro is showing them as sRGB! Some other image in the same Project that were scanned as black and white negative TIFFs were imported but are not editable. These TIFF/DNGs have transferred and are editable. "Scanned as positives" means treating the negative as if it's a transparency/reversal/slide film this initiates a different part of Vuescan. On most of the black and white images that did transfer there's a little grey and orange cross in the corner of the preview, and these images do not appear to be editable! C1Pro shows the "color space" for these images as SRB, but Aperture and Preview show the colour space as Grey and the color profile as blank.Īnother set of images were scanned as positives (TIFFs or DNGs) as well as negatives (JPEGs). It's a 16-bit TIFF, if that's what you meant the corresponding JPEG (obviously 8-bit) is exactly the same pixel dimensions, scanned on the same scanner at the same time but did not transfer. I've just checked the pixel dimensions of one of the latter: 3328 x 2264 pixels. The first part of you message is a bit confusing, although I'm sure this is me just being a bit thick (or at least, unused to C1Pro)! There was one folder of black and white scans, for example, where some were scanned to JPEG and some to TIFF. I have had a look at Preferences and the edit JPEG (and TIFF/DNG) boxes are all ticked. Set, change output image quality or size.Īll common picture and graphics formats are supported (JPEG, TIFF, PNG, GIF, WEBP, PSD, JPEG2000, OpenEXR, camera RAW, HEIC, PDF, DNG, CR2).Thanks Robert.
