frasercameron Posted February 12, 2018 Share Posted February 12, 2018 Hello. I am doing large format collages and was wondering what is the best file to use when I'm saving pictures to add later to the collage, for best resolution. Thank you.

Alfred Posted February 12, 2018 Share Posted February 12, 2018 JPEG is very efficient for photographic images, but since it's a lossy format you should only export to JPEG when the image is in its final form. The larger the format of the collage, the lower the resolution you can get away with (because no one is normally going to view a large picture from very close up).

Reggie1958 Posted February 12, 2018 Share Posted February 12, 2018 Hi Fraser, I have made such a collage ... no expert mind I was asked by a friend to crate a collage of photos she took with alphabetical letters as her insperation .. that's the English alphabet, be interesting trying to get the letters Ö Ä Ü in photographic form .. now there's a project. Anyway..... I had a bunch of RAW files from her and used Affinity photo to create the collage; I found working in 32bit (HDR) colour format for each file made for a truely massive .afphoto best to export to 8 bit JPEG highest quality .. still big files .. or 16 bit Tiff files if you have the computer to handle the massive files. I worked in the highest resolution my computer could handle with the converted RAW filies into 16bit Tiff files then I created my collage .... we are talking a simply huge .afphoto file .. then when done I exported the final document as an 8bit jpeg file best quality. Thus the workflow was to maintian the highest resolution until the end export for printing .. that's another story .. Hope that helps and if there are any experts out there who want to give thier wisdom I'd be grateful :-D Reg.

frasercameron Posted February 13, 2018 Author Share Posted February 13, 2018 Hi Alfred and Reggie. Thank you both very much for your insight. I have been saving them as TIFF files, so that's good to know. I'm a bit confused about outputting to JPEG for a large print though Alfred. Wouldn't TIFF be a better way to go as the resolution is higher, despite the fact that people would view them from far away? Cheers! Quote Link to comment Share on other sites More sharing options...
Alfred Posted February 13, 2018 Share Posted February 13, 2018 I’m not sure what you’re saying, Fraser, unless you’re using the term ‘resolution’ to mean something different from what I understand it to mean in this context.

The issue here is how much detail human vision can resolve, which varies with viewing distance. Technically, determining that accurately is very complicated (see for example this discussion about how differently cameras & humans "see" things) but basically it comes down to determining the approximate distance where we can no longer see individual pixels, or for lossy formats like JPEG where we can no longer see the artifacts lossy compression causes, like blurred edges, ringing, & halos. The bottom line is including more detail than we can see at a given viewing distance won't make anything better.

frasercameron Posted February 13, 2018 Author Share Posted February 13, 2018 Ah, OK. Thanks R C-R. It's starting to make sense. Appreciate the replies! Cheers. Alfred 1 Quote Link to comment Share on other sites More sharing options...
Petar Petrenko Posted February 14, 2018 Share Posted February 14, 2018 You should use the native format of the software you use: Photoshop = PSD (TIFF), Affinity Photo = afphoto, ...

Petar Petrenko Posted February 14, 2018 Share Posted February 14, 2018 Another nice format is JPG2000, but it is not supported by most vendors. It has better compression than JPG and it is losless.

frasercameron Posted February 14, 2018 Author Share Posted February 14, 2018 Thanks Petar. The native format sounds like a good way to go in Affinity. Petar Petrenko 1 Quote Link to comment Share on other sites More sharing options...
