Can anyone think of a reason why Adobe ACR (latest cc version) is only correcting for chromatic aberration when opening RAF (RAW) files from Fuji X-T1 with 35mm f/1.4 lens and not applying a correction for distortion or vignetting? There is no separate lens profile available as I understand it, Adobe simply apply what Fuji supply in the RAF file. An information box bottom right corner in ACR confirms it "The RAW file contains a built-in lens profile for correcting chromatic aberration. The profile has already been applied automatically to this image." I have seen other people comment that the box (for other Fuji lenses) sometimes states "chromatic aberration and vignetting". When I open RAF files from my Fuji 50-140mm f/2.8 the box states "distortion, chromatic aberration and vignetting". Are Fuji suggesting that the 35mm f/1.4 is free from distortion? It clearly isn't, I use it every day to document books and artwork, almost always with lots of vertical and horizontal lines in the subject, and there is often very significant distortion (barrel). At the moment I have to adjust the distortion manually which is very time consuming. I have the latest firmware loaded in the X-T1 body and in the lens, and am using the very latest version of Photoshop CC and ACR. Any ideas? Marc
Hi I'm new to Alamy having sold work through exhibitions, retail outlets and print requests for a number of years. I am finally getting round to putting up a different selection of my images here, however, I have to admit I am feeling very apprehensive about submitting that first test batch of images that undergoes close scrutiny. There are two areas I am mainly concerned with: Sharpening - this seems to be quite an issue and having searched the forums here and on google there seems to be two trains of thought...a) that absolutely no sharpening is allowed by Alamy or that it is output sharpening that should be avoided and that a very small amount of sharpening is ok at the Raw file stage in ACR. I really just want to know if there is an up to date definitive answer to this one as I have always in the past applies a small amount of sharpening to my files in ACR (as well as using a tripod when capturing an image) generally using the following settings - amount 25, radius 1, detail 25, masking 0. Is this ok, does anyone have any recommendations re lower settings or is it an absolute no-no? Size - matters! I just want to clarify that I've got it right in my mind on this one. My understanding is that the uncompressed image size has to be +17mb. I found a calculation on the forums that says that if you take your 8bit, 300dpi image dimensions and multiply them together, multiply that figure by 3 and then divide by one million you get the uncompressed file size. As an example taking one of my old images taken on a 40D this would be 3888 X 2592 X 3 divided by one million = 30.23mb uncompressed file size. Am I on the right lines here or should I be upsizing the file when it is a tif? The reason I ask is because the actual 8bit, 300dpi jpeg I would upload to Alamy works out to be only 4.59mb compressed - is this ok? My cameras used are a Canon 40D, a 5D Mk 2 and now a Fuji Xpro-1. Any advice, guidance or recommendations would be really appreciated - I am a newbie so please be gentle with me Many thanks Lin
