James: A question for you. It appears that photos that I post to Lenspiration have saturation added to them on your site. When I look at what I post vs what is on my pc; the posted images are more saturated.

September 20, 2014 at 10:37 am #7592Ezra MorleyModeratorNice flowers! I just saw some like that recently, and contemplated photographing them, but didn’t.
On first glance, the thing that struck me was the cluttered/distracting background. There are so many bright spots competing for your attention that you don’t know where to look. Add to the fact that there are 3 or 4 flowers more or less in focus, and you just sort of look hopelessly about the image, trying to find something to look at. I run into this problem all the time, especially with smaller flowers. Most of the time I find one good specimen, then try to find a way to isolate it against an uncluttered background. Sometimes a telephoto lens can be helpful in this regard, since the narrower the FOV, the less elements that can get in the frame to be distracting, PLUS, the more you zoom, the less depth-of-field you’ll get, thereby blurring the background further.
I think one of the best things you could do in flower photography is use a tripod. It will slow you down, which will hopefully result in more time spent thinking about composition, angles, backgrounds, etc. Plus, you don’t have to worry about camera shake! (Although you obviously didn’t have any problems with that in this particular shot.)
I love to use an old manual focus prime lens along with a tripod for flower shots. With an aperture of f/2, it’s not hard to make the background disappear into nearly nothing.
September 20, 2014 at 10:47 am #7593timtamParticipantThis one was the uncluttered shot. Not sharp at all. Didn’t use a tripod. I was just stopping at a rest stop for a few minutes. Next time I’ll take the time. I did have a tripod in my car. Should have used it with a diffuser which I also had with me.

October 14, 2014 at 10:01 am #7829James StaddonKeymasterHey @timtam, just now looking through some of these topics from September. I’ll look into the auto-saturation for you!
And yes, I like the second shot for the same reasons as @buddingphotographer mentioned, but I SO do exactly what you said . . . all the time! Something catches my eye in a random place, I have all my equipment close somewhere, but I just don’t think it’s worth the time to get it all out. 🙂 How full my archives are of “almost” pictures that may have been “perfect” pictures if only I had not thought so highly of my hand-holding abilities. Next time . . . that’s what keeps us shooting I guess. 🙂
October 14, 2014 at 4:16 pm #7847Ezra MorleyModerator@timtam : I have a couple of theories regarding,
photos that I post to Lenspiration have saturation added to them.
First, you are looking at them on the same monitor, I presume? That would be be my first thought, is that you saw them on another monitor which was calibrated differently.
Another thing that could have happened, is that you are seeing them against a different background which changes your perception of the coloring in the picture. I set up a test which you can view here, showing a picture against multiple backgrounds. (Tip: hit F11 on your keyboard, to set your browser to fullscreen, so there aren’t any distractions.)
If not, have you downloaded the “saturated” one to your harddrive and compared them side-by-side? That would be an easy way to see if there is actually any “saturating” going on. You can use Fast Stone Image Viewer, (which I highly recommend) to select the two images and directly compare them side by side.
I’ve uploaded a jpeg with a colorful gradient, which I shall then download and compare to the original. If Lenspiration does indeed change it, then I will hopefully be able to tell the difference. Here’s a link to the same image hosted elsewhere.
October 14, 2014 at 4:44 pm #7849Ezra MorleyModeratorOk, so I took that same image which I just uploaded, and downloaded it to compare it to my original. I did a checksum comparison, and they are identical. You can compare them yourself if you like. SHA-1: eebf1ead07e005f00d5961c52e531ef383de01fb
A visual comparison doesn’t reveal any differences either.
Just for fun, I took the original and added some more saturation, then compared them. The checksum changed, and there is a visual difference also. Here’s the checksum for the extra-saturated one: SHA-1: 6b51e43adb19effa4232eb825d853456bae12286 Again, here’s a link to one hosted separately from Lenspiration.
October 15, 2014 at 7:38 am #7862James StaddonKeymasterConcerning the saturation upon upload @timtam, my website developer replied with this response: There is no saturation being applied to photos uploaded. However, an online search suggests making sure that photos being uploaded to the web are saved in an sRGB color space. Other color spaces are designed for print and will appear differently when viewed on the web.
If a problem still persists, then perhaps it would be advantageous to explore your complete upload process.
And thanks for running those tests @buddingphotographer. It’s nice that the developer’s answer is scientifically proven now. 🙂
October 17, 2014 at 10:46 am #7897Ezra MorleyModeratorI didn’t even think about the color-profile difference! So here are some more tests!
You can identify the different color spaces from the file names… As far as my test goes, I can’t see any visual difference in saturation. If you zoom in really close, and switch quickly between them, you can see slight variations in jpeg compression, noise, and what not, but I am not seeing any increase or decrease in saturation. (Using Pale Moon Browser. Version: 25.0.1 [x86])
October 17, 2014 at 11:34 am #7901Ezra MorleyModeratorNow that’s interesting! The originals all look about the same, but the thumbnails that Lenspiration.com generate really look weird! When viewed with Jeffrey’s Exif Viewer the thumbnails don’t have a color space at all, not even sRGB, so that must be the problem! As long as you set the Lightroom export preferences to sRGB, they should look about the same no matter which software you use to view them, as long as you’re using the same monitor.
Here’s some reading on the subject: Which color space should I use? and Digital-Image Color Spaces
(There’s nothing you can do about the thumbnails, those are automatically generated by WordPress. At least make your originals right, and the thumbnails will just have to cope 🙂 )
BTW, I took a look at several of the most recent pictures from @timtam, and they all seem to be in the sRGB color space…
