  1. Thee are usually a bunch of different ways to do things, I agree. Apply Image must be partially broken in Lab equation mode on the Mac in V1.7.2. I can use Lab equations (DL = SL, Da = 0.5, Db = 0.5 - if you do all SL, you get a color image that reflects the mix of the a and b channels) to generate the equivalent of the L* channel. Let's say I want to apply a Curves adjustment through an inverted L* mask, a typical task to boost shadows or target shadow tones for color correction, etc. So I have a layer stack that has the working image (background layer) and a curves adjustment layer above it. Recall that adjustment layers have their own inherent mask built in. So, I select the Curves adjustment layer to make it active (the target of the Apply Image command): 1) Open the Apply Image dialog (Filter > Apply Image) 2) Drag the background layer onto the dialog box to make it the source of the Apply Image operation 3) Use Equations - DL = SL, Da = 0.5, Db = 0.5, DA = SA And apply image. The result gets applied to the mask of the Curves adjustment, but the resulting image is distorted and scaled up and is not the L* channel of the background. (see attached screenshot). To make this work properly, I have to create an empty pixel layer and generate a pixel-based representation of the L* channel - i.e., new pixel layer, fill it with white, then do the apply image operation to generate the L* channel on this pixel layer (the second screenshot is what the L* channel should look like). Then I have to rasterize it to a mask, then drag it to the curves layer. That is a lot of steps for a simple operation. The use of the Levels filter with your settings at the top of the stack will also generate the desired L* output, but then you have to stamp the layer stack, rasterize the resulting pixel layer and then apply it as a mask. It is a nifty way of doing things though. I prefer the Duplicate Image method because I can work in Lab mode with Lab tools to choke the mask, etc. and then simply apply the L* channel to the working master image (to an adjustment layer or as a pixel-based layer, etc.) when I am finished in the duplicated image. I can also leave the duplicate image open and tweak the operations and reapply the result to refine or edit the result for use in the original. Kirk
  2. I second this request. The Photoshop equivalent is Image > Duplicate and is useful for myriad tasks, especially when you want to perform an action or a color mode change for a particular purpose and then introduce the result back into the master working document without having to Save As... and create another file in the OS (for example, you would like to create a mask from the L* channel of your current RGB document - dup the current RGB document, change the dup's mode to L*a*b*, and Apply Image > L* channel to the RGB doc's active layer as a mask). The duplicated version is simply a document that exists in memory and is usually something that is temporary or can be saved after the fact if that is its intended purpose (for example, if you create an action that duplicates the master document, flattens it, reduces the size and performs output sharpening and color space change for output). This seems like a no-brainer and I am repeatedly surprised after major updates that AP has not implement this. Kirk
  3. You can export 16bit TIFFs of each channel from Raw Digger, using the option to fill in the missing pixels with zeros (black). Then you can open each of the four channel TIFFs (R, G1, B, G2) and convert them to 32bit (they are linear) and stack them in linear dodge (add) mode - for each of the four layers, you can clip a recolor layer to add the CFA color that corresponds to that layer. This will effectively give you a UniWB image - you can clip an exposure adjustment to the R and B layers and adjust the exposure of R and B to white balance the image. kirk

    You will have to use Adobe DNG converter on a PC or Mac desktop - there is no iPad version. However, you can batch convert RAFs from your older S5000 and then make them available to your iPad through a number of different transfer/storage paths, including iCloud, Dropbox, a WiFi accessible drive, Airdrop, etc. Once you convert your files to the appropriate form of DNG and upload them to your preferred storage/iPad accessible location, you are good to go. Easy peasy. Astropad is simply an application that permits you to use your iPad as a second display, a feature that the upcoming MacOS will have built into it. It does not permit you to transfer files to the iPad, etc. kirk

    I was able to convert the raw file in AdobeDNG Converter using some custom settings: (Change Preferences > Custom (Compatibility) > Backward Version DNG 1.1, Linear (demosaiced). Play around with the custom compatibility settings to see what works best for your workflow. In this example the raw data were demosaiced, so the file has been rotated appropriately. Attached is a screenshot of your raw file, converted to DNG, opened in the Develop persona. Here is a Dropbox link to the converted DNG: https://www.dropbox.com/s/0rfzunzpx8jxk6i/DSCF2600.dng?dl=0 kirk

    Ok - the camera uses the Fujifilm SuperCCD, which has its quirks. I was able to use a Mac desktop application called LumaRiver HDR (meant to blend raw exposures into a single HDR DNG, TIFF or EXR). This application must use a more robust technical implementation of the DNG API, because I was able to open your raw file in it and then export a DNG from it that I was able to open in AP on my iPad. Here is a link to the DNG: https://www.dropbox.com/s/rfdzu8z3fi9ty1r/testDNG.dng?dl=0 and attached is a screenshot of the DNG opened in the Develop persona in AP on the iPad (Import from Cloud, loading the file from my Dropbox). The image is rotated 45 degrees because of the orientation of the photo sites on the sensor of the SuperCCD. kirk

    The Fujifilm Finepix S5000 is a pretty old camera. There is a raw converter for MacOS and iOS called Photo Raw - here is the camera support webpage: https://mcguffogco.freshdesk.com/support/solutions/articles/8000063657-supported-cameras the list of supported cameras includes the S5000; however, I cannot open your file with Photo Raw. Perhaps the file itself has an issue that is causing applications that would otherwise support it to fail to recognize the file format or open the image. Do you have other raw files shot with this camera available to test, or, even better, do you still have the camera and can you update it to the latest firmware and shoot some test images to try? kirk

    @Rob Chisholm Bummer. Obviously it would be nice to have AP work properly on the iPad, but in the interim you might want to try using Raw Power as a raw converter for iPad. It is made by the former lead of the Apple Aperture application and has a similar control UI. kirk

    I had the same issue with my new iPad and my x-h1. Restart your iPad (shut it down and turn it back on). Then try again. Worked for me. I found this solution in another similar thread in the forum. The mod was puzzled as to why it worked, but it worked. Who knows what the iOS is doing to adapt to the user in the background. Kirk
  10. Try: 0) Open the App Store and make sure that you do not have updates for AP or AD pending. 1) Restart your Mac. 2) Launch Publisher, Designer and Photo so they are all running. Then, in Publisher, drag an image onto the page (create a new document if you have not already), select the image and click on the Photo persona button in the upper left corner of the Publisher window. You should get the Photo tools to edit your image as if you are in Affinity Photo. The ability to dip in and out of the various personas all within a single application is next level stuff. Nice work Serif folks. Kirk
  11. I apologize - it looks like this topic has been covered, with the answer being that I need to update the App Store versions to the latest version (1.7.1) of Photo and Designer, which are available now. The Mods can delete this topic if they would like. Kirk
  12. I purchased Photo and Designer a while ago through the Apple App Store and purchased Publisher through the Affinity webstore. I just was able to download Publisher (congratulations Affinity!) and have found that Studiolink does not "see" my installs of Photo or Designer. Do the App Store and Affinity Store versions of these applications play nice through Studiolink, or will I have to purchase Photo and Designer again through Affinity to get the Studiolink functionality? Thanks, Kirk
