RBTSMPSN Posted October 4, 2021 Share Posted October 4, 2021 My daughter is a high school cheerleader and I take pictures of all the girls at each game and upload them to Dropbox for all the parents, coaches, and the school’s yearbook staff. After I uploaded a batch from the last game I noticed there were a few images with much lower file sizes. I shoot RAW, develop in Affinity Photo on my iPad Pro, save as a JPEG to either my camera roll or an external hard drive, then upload to Dropbox. The images are always between 18 and 24mb, depending on the crop. But this time there were a few that were 8-10mp. In Affinity Photo I make my adjustments in the Develop Persona and the only other edits I do is with the clone tool or in painting brush. I opened the smaller mb images to see what was different with these images and noticed that each of them were ones I’d applied a filter to. They either had the depth of field blur added or a vignette added. I rarely add filters. Curious. Why were the images I added a filter to reduced in size when I exported from Affinity Photo? Thanks.

Staff DWright Posted October 5, 2021 Staff Share Posted October 5, 2021 The JPEG file format is a lossy compression format so if you apply an adjustment such as a blur when you export the photo there will be less information in the photo to be exported and this causes the file size to decrease Quote Link to comment Share on other sites More sharing options...
