  1. Buon giorno, scrivo questo post per riprendere due post precedenti che sono comunque interconnessi, chiedo agli amministratori di chiudere i miei due post precedenti. Uso un altro software con licenza GNU / GPL, o "darktable", e lo uso per una semplice ragione, sfruttando la libreria lensfun che è presente anche in affinità ma che è in grado di applicarla anche su file jpeg e usando un software gnu / gpl adattato allo scopo "ShitfN" per correggere le distorsioni prospettiche attraverso il rilevamento in gruppi di linee di fuga, sia che si tratti di linee verticali o verticali oblique, riesce a farmi guadagnare tempo prezioso nel correggere distorsioni e prospettiva, dato che Affinity ora applica il profilo dell'obiettivo solo ai file raw e non direttamente ma dopo il salvataggio, il che è scomodo, ma per me ancora poco pratico poiché utilizzo una fotocamera "Sigma".Inoltre Affinity per ora non ha una funzione di correzione della prospettiva automatizzata o almeno non di quella che funziona così bene, il risultato è che ogni volta che devi procedere a mano e in termini di tempo, diventa insostenibile ogni volta che devi cambiare un numero pieno di immagini. Chiedo quindi che, dal momento che questi due software, la libreria lensfun e ShitfN siano open source, fare uno sforzo e adattarli il prima possibile in quanto ciò fa la differenza tra un programma comodo e quindi utile e un programma bello ma non completo. Metti un video come richiesto, in modo che tu capisca di cosa sto parlando. Grazie Lorenzo correzione dell'obiettivo prespective correction.mp4
  2. This issue pertains to the Sigma dp0 Quattro which I own, and almost certainly also pertains to these other Sigma cameras on the Supported list: dp1 Quattro, dp2 Quattro, dp3 Quattro, sd Quattro. The problem is the same in Affinity Photo 1.4.3 and 1.5 Beta 6, installed on my Apple MacBook Pro Retina 2012 with Sierra OS. I want to thank the Dev team for tackling Sigma cameras at all. I know other Sigma camera owners are also grateful, as hardly anyone is tackling the Sigma X3F raw files in their raw processors, and the Sigma software is slow, ungainly and has very limited features. I also encourage the Dev team to tackle the current-model Quattro cameras I listed above, before tacking older Sigma cameras. THE PROBLEM: the rendered output has a very poor appearance when zoomed in. Even though the files are the full resolution, they look as if a 'coarse effect' or a 'low-resolution overlay effect' has been applied. The effect is so severe that the files really are unusable for Sigma camera owners. I have posted sample images including comparison with the straight-out-of-camera JPEG images, here: https://www.dpreview.com/forums/post/58608616 Please compare the camera JPEG with the Affinity file at 100% to see the magnitude of the issue. I am calling this a bug because, even though Affinity Photo 'works', it produces something unusable due to image quality issues. thanks

    Black screen DNG

    I get a black photo when opening a DNG file of a RAW photo, shot with my Canon 80D and the Sigma 18-35mm f/1.8 lens, in Affinity Photo for iPad. See enclosure. Is DNG not supported?
  4. Since the recent update I can import RAW files. Thanks for that! :) The Canon 80D RAW photos I tested with Affinity Photo for iPad that I shot with the 55-250mm STM are of high quality. The Canon 80D RAW photos taken with the Sigma 18-35mm f/1.8 lens are of very poor quality when opened in Affinity Photo on my iPad Pro 12.9". See enclosed example. The colors are wrong, there is a lot of yellow in the highlights. Is this a bug?

    SD Quattro X3F color problem

    Good morning I noticed an obvious difference of tone by opening the same X3F raw file with Sigma Photo Pro and Affinity, which may be the problem? Trying to change settings in the sRGB color profile to ProPhoto RGB course the situation improves but is not solved. Lorenzo
  6. Hi Affinity Photo Team, When I open X3F files from my Sigma DP2 Merrill, I am met with green tint all over some photos or at outer circular areas around the center. Am I doing it wrong? Is there anything I can do for work around at the moment? If this could be fixed, it would be really awesome. n
  7. Hello, I'm HalbLeiter. Today, I experienced strange problem in the EXIF of the image I've taken. I'm using Nikon Df and SIGMA Art 24-35mm f/2.0, and the images were taken with the RAW(.NEF) format. When I opened these images with the Affinity Photo, the lens data were shown (ex. focal length, aperture) but the lens maker and model were not shown. I also made questions to the lens maker(SIGMA) and camera maker(NIKON). Answer from SIGMA: This problem is related with the camera maker. Maybe the camera maker have no information about the newly released lens on the look-up table. However, we don't have permission to tweak the firmware on the camera. Please ask to the camera maker. Answer from NIKON: In original, we(NIKON) are not supporting 3rd party accessories such as lenses, batteries and speedlights. In other case, when the camera body cannot recognizes the lens, the lens maker is updating their firmware to make recognizable. Please ask to the camera maker. How do you think about this? _DSC7569.zip
  8. I'd like to to know if Affinity accepts the raw files- X3F- from a Sigma Quattro dp2. I'm especially interested in local adjustments. If not, do you have plans to include it in your list of raw files anytime in the near or not so distant future ? Thanks
