Mastering Darktable: How To Export Stunning Images Like A Pro!

[@rosleinrot5322]

Thank you for the explaining of the export procedure in dt. For me it is very useful to hear about the differences in the parameters.

My pleasure, glad it helped!

Re: 'set size' option. I often create panoramas from several tiff images which can make a huge file. I resize the tiffs by entering a decimal fraction here, e.g. 0.75, 0.5, 0.25 etc. This also maintains the aspect ratio. You can also upsize which surprisingly does not seem to degrade the image. Thanks for a very comprehensive treatise of an extremely complex aspect (in terms of options) of dt.

Thanks for a great video, as ever. A word to the wise as to resizing if you’re publishing to Facebook. Not that I’ve done it yet, but word on the street is that you need to upload a file where neither of its dimensions is greater than 2048. If you exceed this then Facebook will apply its own resizing algorithm and the technical term for the result is “crap“. So set the first dimension to 2048, leave the second at the default and you’ll get a result with the same aspect ratio. I imagine you would want the sRGB profile as well, but I’ve yet to test this.

When you export an image and then send it by email or a FTP is the metta data included? If not, how do you include the data?

[@AndyAstbury]

By metadata I take it you mean EXIF and IPTC? Camera data, title,caption, description and keywords can all be entered for an image, and export with the image no problem. Keywording is possibly the poorly thought out and executed - certainly not the easiest I've used - but it does work.

Thanks Andy for clarifying all these options. I submit images to picture libraries. They require 8bit jpegs and always in the Adobe RGB 1998 colour space [obviously all images going to print]. dt refers to Adobe RGB (Compatible). Is this the same thing? Thanks again for all your informative videos, Best regards Alan.

[@AndyAstbury]

Hi Alan, I sub to stock sites, always jpeg, and always in the sRGB colour space, which is the correct colour space for jpegs. AdobeRGB1998 has a gamma curve of 2.2, which is better for for 16bit files but is too contrasty in the shadows and highlight for 8bit images with only 256 levels per channel. The sRGB native gamma is a hybrid gamma curve that only AVERAGES 2.2. This way, your jpegs look better, basically.

@@AndyAstbury Thanks for your time to reply Andy. I supply to only two agencies, one in Germany and the other here in SA. Both their submit guidelines stipulate 8bit and Adobe RGB and in photoshop, as u know it's listed as that. I'm trying to use darktable but it's listed as "compatible" and I wondered why. Anyway thanks again Andy 👍 best Alan.

Test comment.... I have left the same comment twice now and when I come back no sign of it... comment was regarding rendering intent in DT....default srgb profile does not support it... just a heads up... let see if this comment sticks... if not I am very curious why.....

[@AndyAstbury]

Hi Todd, not had any previous comment from you turn up recently - I've set you as 'approved' now, so your future comments should show immediately

[@emrg777]

All good Andy...just left that comment on rendering as many people assume it works... and it does just not with the default sRGB profile included with DT.... no worries ... I enjoy your videos...
