Does anyone know why when I upload my picture onto the site the colours look very different to how they look on my hard drive? I've never had this problem before?
Could be the way 365 is compressing the file when you upload, making it more web friendly. Lower compressed images will have better load times across all platforms.
Oh right. I think it must be the compression thing as @sbarriere said, but I'm not going to re-edit just for the site. It's no biggy, I just wondered why the colours looked so different, as I've never had a problem with it before. @chedarrooed
If you are converting from a high dps or high pixel image to a smaller one and the file is a .jpeg, it's considered a "lossy" file. What this means is that the larger files have more color depth and options when picking the hue, and that when you convert to a smaller file, the converting software "drops" colors and clarity in order to get a smaller image size. You "lose" pixels in the conversion.
Are your pictures slightly less sharp as a result of the upload? Sometimes lossy files blur edges during the conversion as well.
Thanks for commenting Thomas. Yeah loss of some clarity, but barely noticeable, but the loss of richness in the colours is. The uploaded version looks really wishy-washy.
I probably wouldn't have noticed otherwise, but I'm going for an autumnal/fall theme and the colours are one of the main focuses. @thomastoth
Yes it's some kind of compression, I noticed my colours just don't look vibrant enough and wishy-washy as you said, probably why I mostly upload mono photos here :D
Miley, what color profile are you using on your camera versus post processing and uploading from your system? This can make a different. Look for setting like Adobe RGB (1998), Apple RGB, ProPhoto RGB and sRGB IEC61966 2.1. Have them set the same and when you output to JPG.
I'm going with Mike on this. I shoot for internet color and the files stay the same. But if you choose a shoot for print and then upload them to the internet, you will get a shift in color everytime.
@miley89 Miley, there was a similar discussion about a month ago, and Mike @mikegifford has the response that matched that discussion. You want to make sure your color profile is set to sRGB across the board. Uploading to this site eliminates the color profile, and that is the default.
Mine do the same thing and it has nothing to do with color profiles.I shoot raw which doesnt have a color profile in camera and not until i bring it into lightroom which i have set to sRGB on import and export. So i work entirely in sRGB. I can load the same sRGB jpeg to facebook and then on here open them both up side by side in the same browser and they look different. The one on facebook looks exactly like my hard drive but on here always gain a orange tint. So that has nothing to do with the browser or color profile it has to do with how this site is compressing and processing files i think.
Mine are not as sharp on 365, besides the color issue. Though I guess if the colors are not being read correctly, then info is missing and lack of sharpness makes sense. It's just so lame though
people have a variety of cameras and take shoots in a wide variety of sizes.. but websites display pictures in a limited size format, usually restricting the size of the largest side of the pictures...
so if you are uploading pictures as you shot them, lets say for example 6000x4000 pixels and the maximum size allowed in the website is 1000 you picture will be reduced 36 times (6x6).. your picture will look a little blured and "different".. so every website has his own algorithm for resizing the pictures and tryy to "correct" them after resizing for the pictures to look good... so that may cause you to feel that your picture looks slightly different....
the other thing is colour profile and DPI.... probably your camera is shoting and storing picture with 300 DPI (dots per inch) and using adobeRGB colour space to store the colours info.. and websites use sRGB colour space... so maybe this is the main reason you feel your coulis are different after uploading
my explanation maybe has some errors or imprecisions but this is more or less what happens...
I always change my pictures myself before uploading to websites like this one or Flicker or whatever... what do I do? (to avoid the websites algorithms to "ruin" the picture.. i do the job myself before uploading...
after the edition is finished and before saving the file for upload I do: ( I use photoshop but other editors have to have similar options)
1. In Image - Resize- i change the DPI to 72
2. I resize the largest size to around 1024 pixels. If you change the DPI to 72 after resizing you will end up with a thumbnail.. DPI change has to be before changing the size to 1024)
3. I go to filters - Sharpen - Unsharp mask and use the values 30% and 1.0 for pixel radius - to rebuild the sharpness and avoid the bluring the resizes provoques.
4. In Editt - Coonvert to profile I change the destination space to sRGB
5. save
this way the uploaded image is "ready" for website publishing and avoids better the "damage" of the website's conversion / resizing alghoritms

I hope this helps! :)
