Heiko R."Sunny Days"A little too bright in the highlights, but that's just what you get when you take photos with a today 18 years old Sony Alpha 100. And yet I'm somehow obsessed with these old cameras and their image sensors. 🤭Cam: <a href="https://heikosart.eu/search?tag=SonyAlpha100" class="mention hashtag" rel="nofollow noopener" target="_blank">#SonyAlpha100</a> dslr Developed from <a href="https://heikosart.eu/search?tag=raw" class="mention hashtag" rel="nofollow noopener" target="_blank">#raw</a> w/ <a href="https://heikosart.eu/search?tag=digiKam" class="mention hashtag" rel="nofollow noopener" target="_blank">#digiKam</a> & <a href="https://heikosart.eu/search?tag=libraw" class="mention hashtag" rel="nofollow noopener" target="_blank">#libraw</a> on <a href="https://heikosart.eu/search?tag=OpenSUSE" class="mention hashtag" rel="nofollow noopener" target="_blank">#OpenSUSE</a> Tumbleweed <a href="https://heikosart.eu/search?tag=Linux" class="mention hashtag" rel="nofollow noopener" target="_blank">#Linux</a>. <a href="https://heikosart.eu/search?tag=CherryBlossom" class="mention hashtag" rel="nofollow noopener" target="_blank">#CherryBlossom</a> <a href="https://heikosart.eu/search?tag=CherryBlossoms" class="mention hashtag" rel="nofollow noopener" target="_blank">#CherryBlossoms</a> <a href="https://heikosart.eu/search?tag=sunnyday" class="mention hashtag" rel="nofollow noopener" target="_blank">#sunnyday</a> <a href="https://heikosart.eu/search?tag=SonyA100" class="mention hashtag" rel="nofollow noopener" target="_blank">#SonyA100</a> <a href="https://heikosart.eu/search?tag=dslra100" class="mention hashtag" rel="nofollow noopener" target="_blank">#dslra100</a> <a href="https://heikosart.eu/search?tag=rawphotography" class="mention hashtag" rel="nofollow noopener" target="_blank">#rawphotography</a> <a href="https://heikosart.eu/search?tag=naturephotography" class="mention hashtag" rel="nofollow noopener" target="_blank">#naturephotography</a> <a href="https://heikosart.eu/search?tag=Naturfotografie" class="mention hashtag" rel="nofollow noopener" target="_blank">#Naturfotografie</a> <a href="https://heikosart.eu/search?tag=digitalsnap" class="mention hashtag" rel="nofollow noopener" target="_blank">#digitalsnap</a> <a href="https://heikosart.eu/search?tag=olddigitalcameras" class="mention hashtag" rel="nofollow noopener" target="_blank">#olddigitalcameras</a><a href="https://heikosart.eu/search?tag=photography" class="mention hashtag" rel="nofollow noopener" target="_blank">#photography</a> <a href="https://heikosart.eu/search?tag=DevelopedFromRAW" class="mention hashtag" rel="nofollow noopener" target="_blank">#DevelopedFromRAW</a>

Heiko R.<a href="https://chaos.social/users/schenklklopfer" class="u-url mention" rel="nofollow noopener" target="_blank">@schenklklopfer</a> <a href="https://heikosart.eu/search?tag=digiKam" class="mention hashtag" rel="nofollow noopener" target="_blank">#digiKam</a>! Mit <a href="https://heikosart.eu/search?tag=libraw" class="mention hashtag" rel="nofollow noopener" target="_blank">#libraw</a>. Für normales Entwickeln bietet sich das einfach nur an. Jedoch, auch <a href="https://heikosart.eu/search?tag=rawtherapee" class="mention hashtag" rel="nofollow noopener" target="_blank">#rawtherapee</a> und <a href="https://heikosart.eu/search?tag=darktable" class="mention hashtag" rel="nofollow noopener" target="_blank">#darktable</a> lassen sich prima einbinden.Für mehr HDR-Spielerei greif ich auch gern noch auf das gute, vor allem aber alte (😊) <a href="https://heikosart.eu/search?tag=LuminanceHDR" class="mention hashtag" rel="nofollow noopener" target="_blank">#LuminanceHDR</a> zurück. Aber das hat mit Alternativen zu Lightroom schon nix mehr zu tun. :smile:

Heiko R.<a href="https://graz.social/users/norberteder" class="u-url mention" rel="nofollow noopener" target="_blank">@norberteder</a> DarkTable und <a href="https://heikosart.eu/search?tag=RawTherapee" class="mention hashtag" rel="nofollow noopener" target="_blank">#RawTherapee</a> bzw. <a href="https://heikosart.eu/search?tag=Art" class="mention hashtag" rel="nofollow noopener" target="_blank">#Art</a> sind zwar hervorragende und mächtige Werkzeuge, aber für mich hat das für die normale Alltagsarbeit eher was von Kanonen auf Spatzen und so. Ich nehme sie gern, aber nur sehr selten zur Hand.Ich habe mich an die Arbeit mit <a href="https://heikosart.eu/search?tag=digiKam" class="mention hashtag" rel="nofollow noopener" target="_blank">#digiKam</a> gewöhnt. Ist man bereit, sich einzuarbeiten, hat man alles, um sein Archiv vernünftig zu organisieren, plus einige treue Helferlein wie den Bildeditor mit seinen PlugIns/Modulen. Für nicht zu aufwändige, schnelle Korrekturen brauchts nicht viel mehr, so dass ich nicht mehr "für jeden Kleinkram" auf <a href="https://heikosart.eu/search?tag=GIMP" class="mention hashtag" rel="nofollow noopener" target="_blank">#GIMP</a> zurückgreifen muss. Und mit <a href="https://heikosart.eu/search?tag=LibRaw" class="mention hashtag" rel="nofollow noopener" target="_blank">#LibRaw</a> (Voreinstellung beim Rohdatenimport) lassen sich direkt aus digiKam heraus schnell und einfach Rohbilder entwickeln. Unterwegs auf dem Laptop nutze ich das gerne mal.Adobe-Produkte habe ich noch nie gebraucht. Selbst damals, als ich noch WindowsXP (haha, wie die Zeit verrinnt! 😊) auf einer Partition neben Linux laufen hatte, habe ich lieber digiKam & Co. genutzt.Zwar hatte ich irgendeine damalige Photoshop-Version zuhause, genutzt habe ich die jedoch nie. Sorry, welche PS-Version PS das damals gewesen sein mag, kann ich nicht mehr erinnern - ich habe es schlicht und einfach nicht gebraucht. :smile:

StrephilПрислала мне фоточки из горной прогулки, сделанные на её iPhone. Это файлы DNG размером по 65 мбайт фоточка. Что-то многовато для простых фоточек. Хочу их сконвертировать. И тут вот какое дело. Когда я смотрю фоточки просмотрщиком Geeqie — фоточки яркие, красивые. Но когда я конвертирую их с помощью ImageMagick, фотографии получаются блёклые, тусклые, некрасивые. Это странно, ведь и ImageMagick, и Geeqie использую одну и ту же библиотеку libraw. Попробовал вместо ImageMagick dcraw, получилось лучше, но всё равно не так, как Geeqie. У dcraw есть куча опций, но разбираться в них мне не очень хочется. Geeqie-то показывает красиво по умолчанию. Готов ли уже Linux для десктопа? я не знаю. <a class="hashtag" href="https://juick.com/tag/iPhone" rel="nofollow noopener" target="_blank">#iPhone</a> <a class="hashtag" href="https://juick.com/tag/Linux" rel="nofollow noopener" target="_blank">#Linux</a> <a class="hashtag" href="https://juick.com/tag/libraw" rel="nofollow noopener" target="_blank">#libraw</a> <a class="hashtag" href="https://juick.com/tag/%D1%84%D0%BE%D1%82%D0%BE" rel="nofollow noopener" target="_blank">#фото</a> <a class="hashtag" href="https://juick.com/tag/imagemagick" rel="nofollow noopener" target="_blank">#imagemagick</a>

Simeon SchmaußI also added a bit of code that slices up the color image back into its original bayer array so I can debayer it again with an algorithm that produces fewer artifacts. The original Malvar(2004) debayering tends to produce a grid-like artifact on smooth surfaces and a "zipper" artifact on high contrast edges. VNG fixes those areas but is also less sharp. Eventually I'd like to try AHD debayering via <a href="https://fosstodon.org/tags/libraw" class="mention hashtag" rel="nofollow noopener" target="_blank">#libraw</a> for example.
