strikele Posted September 23, 2019 Share Posted September 23, 2019 In the latest version of Affinity Photo, 1.7.2 from Apple Store, there appears a strange bug. ISO values are incorrect in many cases, but not all. For example, ISO 400 in a TIF file, will be shown in Affinity's EXIF tool as 800 and will be written as such on the exported jpg. ISO 125 will be shown as 72. ISO 640 will appear as 1987 and ISO 1000 as 4935. This occurs with TIF files coming from Canon's DPP 4, on both my Canon G7X mark 11 files and my Canon 77D files. The ISO on the incoming TIF files matches that of the CR2 files. Other programs, such as Xnview show the ISO on the TIF files correctly. In some instances, particularly those with ISO 100, the error does not seem to occur. Quote Link to comment Share on other sites More sharing options...
Staff Chris B Posted September 27, 2019 Staff Share Posted September 27, 2019 Hey strikele, We could really do with some samples. Are you okay to attach some? I always prefer to get user samples as opposed to relying on finding some from the net. We have considered doing some work in this area for 1.8 so whatever you can provide could stand to be quite useful.

strikele Posted September 27, 2019 Author Share Posted September 27, 2019 Chris, I have attached 2 original tif files from Canon's DPP4. IMG_0237 is ISO 400 and shows up that way in AP, and exports as jpg correctly. IMG_0241 is ISO 125 and shows up in AP as ISO 72 and exports to jpg as 72 .

Staff Chris B Posted October 8, 2019 Staff Share Posted October 8, 2019 Hey Leslie, We've had a look at the images and it looks like the info we need is being corrupt during the upload to this forum. Would you mind popping them inside this private Dropbox folder for me instead? https://www.dropbox.com/request/58Uhb2it2KIksPxAsi4N Quote How to format a bug report | Learning Resources | List of V2 FAQs | YouTube Tutorials Link to comment Share on other sites More sharing options...
Staff Chris B Posted November 28, 2019 Staff Share Posted November 28, 2019 Hey strikele, Sorry I hadn't realised you uploaded the images to Dropbox. We don't get a notification sadly. Anyway, I just wanted to inform you that the images were useful and we are looking into the issue—thank you.

strikele Posted November 28, 2019 Author Share Posted November 28, 2019 Sorry, Chris. I should have sent you a note, but the screen I used for update stated you would be automatically informed. Thank you for having a look at it. Leslie Chris B 1 Quote Link to comment Share on other sites More sharing options...
