Done with a high quality Panasonic digital camera. If I have to reduce the pixel count, how do I do that?
Well you're using JPG which has already reduced the quality compared to RAW or TIFF. You don't say what the size of the image is, it's pixel-count dimensions, only the file size. If you used the JPG setting on your camera then you also set the 'resolution' (aka size) there too. You can run the 'file' command, that gives : (edited for clarity) DSCF0279-1-A.jpg: JPEG image data, JFIF standard 1.01, aspect ratio, density 1x1, segment length 16, manufacturer=FUJIFILM, model=FinePix F600EXR, datetime=2013:12:13 11:27:11], baseline, precision 8, 2464x3262, frames 3 ^^^^^^^^^ DSC03367_3.jpg: JPEG image data, JFIF standard 1.01, aspect ratio, density 1x1, segment length 16,manufacturer=FUJIFILM, model=FinePix F600EXR, baseline, precision 8, 428x640, frames 3 ^^^^^^^ Baselline for that camera is 16Mpxl, 4,608x3,456 The editors I use are Darktable and GIMP. My point here is regardless of the 'quality' of the camera, your GIF or JPEG are throwing away details already. The issue is how much is actually relevant. Carlos describes using the GIMP tool's 'export as" to adjust size AND quality of the export. I'd further suggest CROPPING using GIMP so you only export what's relevant. -- “Reality is so complex, we must move away from dogma, whether it’s conspiracy theories or free-market,” -- James Glattfelder. http://jth.ch/jbg
