Based on a Professional Lightroom class I took at Samy's Cameras in Los Angeles, the instructor recommended using whatever color profile your printer or printing lab uses.


That's easy then as I have two HPZ6800's set to use Adobe RBG already and that's what I print on (though I just got a Canon Pixema 10 for home use and am curious to see how well that does).

It sounds like you are not doing any color management at all.

The first thing you need to do is get a Spyder, or better yet, an Xrite i1 Display Pro hardware profiling tool to measure your display and create a table of values that will bring the color into line with a industry standard.

Second, you need to understand that the only browser I am aware of that is color-profile aware is Firefox.

Next, File Explorer and Windows Photo Viewer are not color-profile-aware.

Lastly, if you are shooting raw there is no "color space" - when you bring the image into Lr for editing, it uses a very large color space, similar to ProPhotoRGB, called MelissaRGB, but only in the Develop Module. when you view the image in Library or any other module, the color space is roughly sRGB. You want to work in a large color space for editing, but for output you want sRGB - the lowest common denominator. If you are printing, and you send your files out to a lab, they will use sRGB, and if you send them anything with a wider gamut or greater bit depth, it will be "normalized" to 8 bit jpg, sRGB.

The nice thing about sending prints out is that you can always get a paper/printer/ink profile that is fresh, usually only a day or two old, that you can use to softproof your images in Ps or Lr. You can use the option to "use printer colors" and that will give you a pretty close match to what you see on the screen.

xrite purchased from BH moments ago - this extends beyond my photography into our professional lab which does geospatial technologies - we've been grumping about this in that arena for a while and this should help. Used to use an application called SuperQueue to help do this using paper cards. I was unaware the Windows was color-profile dumb.

Question: - I have always been able to set Adobe RGB on my Canon EOS 5D MIII and now my MIV and the colors seem to agree well moving from the camera to the Adobe suite (though I'm not super skilled with the latter). Are you saying this is a misnomer, I'm not understanding the setting correctly on my camera and in Adobe, or that it's OK for me to move between camera and Adobe using that setting, but when I drop the export out that I should swap to sRGB?

Thanks for taking time here - I appreciate the education.

Friends, I'm about to lose my mind with color management. I shoot RAW with Adobe RBG colorspace, process in Adobe LR and PS. After I export to a jpg at the highest quality, the image's color looks screwed up. I'm attaching a screenshot which shows Adobe PS with the correctly balanced blue sky in one image at right, the Windows File Explorer preview at center, and the Windows Photo Viewer at left. The blue is radically different across the board. While I expect a little variation, this seems excessive. What might be the problem and how can I rectify it? How do I ensure the color is "locked in" to display as I intended when I upload to a service like Facebook or Flickr or submit it for a competition?

Well, since you asked, apply a bit of Denoising to the image. For Photoshop, consider the Nik plugins or Topaz Adjust. Adjust will take a flat image and bring out hidden colors that are present but not readily apparent.


Thanks! I mess with the luminance and chromatic noise tools, but noted that I had to find a balance between the desired sharpness when viewed at 1:1. Do either of those plugins do a better job and where/how do you get them?

From the cockpit at 23,000', Nepal side of the border. Canon EOS 5D MIII, 70mm, f/8. Post-processing with Adobe LR for crop, exposure, de-haze, and color balance.

I typically use Photoshop CS to do post-camera work and am somewhat of a traditionalist with respect to what types of processing I'll do - I try to stick to "normal" darkroom activities such as adjusting exposure, color balance, dodging, burning, cropping, and similar. So I was a bit frustrated with the photos I shot of the Himalayas because I was photographing through a tinted aircraft window in the cockpit and there was a bit of haze. I caved in a bit and started diddling around with Lightroom this evening and found the de-haze tool and was able to sample out the brownish tint from the window based on shots I had of other mountains photographed from the rear of the plane through un-tinted windows. I also like to keep the original photo's ratio intact, but decided that an irregular crop would be OK in this case. Thus I give you Everest, Lhotse, and Makalu. Could use some more LR/PS tips, so feel free to add a few in the comments section.

I'm a Canon Platinum Professional Services member, so I buy a ton of their gear and interact with the company often enough. While B&H is my go-to vendor for initial purchases, I will compare their used department prices and rating against those put forth by the Canon refurbished store. The latter has reasonable prices and they'll give you a 1-year manufacturer's warranty. I've been quite happy. You also need to think about the inherent value in quibbling over anything less than a 4-5% net variance in price among the different vendors vs the confidence you'll have in the purchase. We all like to save money, but is the proverbial squeeze worth the juice in short-term worry factor and longer-term reliability - especially if you plan to use the lens to generate income for a business.

Point-and-shoot as a marketplace, cell phone based or otherwise, will likely moves to multi-lens systems like the L-16 as processing improves and data transfer to cloud storage becomes faster and more widespread (in terms of capable coverage). SLR's will stay, but for composition/artistic purposes. Processing software will become more automated and move off your computer into the camera.

I have they lens mentioned here (exception, my 50mm prime is f1.2 and I use the 16-35mm instead of the 11-24) and this answer is spot on. I shoot a very wide variety of subjects and would be happy to post examples from those different lenses as requested.

The lens you have is an excellent one; the following Canon lenses are all really good (they are also heavy and not inexpensive): EF 11-24mm f-4L USM, EF 24-70mm f/2.8L II USM, EF 70-200mm f/2.8L IS II USM, and EF 100-400mm f/4.5-5.6L IS II USM; the EF 100mm f/2.8L Macro IS USM, and EF 50mm f/2.5 Compact Macro (inexpensive and light) are both very useful, if you want macro. The Extender EF 1.4X III works well with the 100-400 and the 70-200; I understand the Extender EF 2X III is great with the faster zooms and the primes.

You have to decide how you want to take your pictures--there are really excellent primes available, but the zooms offer more flexibility at the sacrifice of usually only one stop of speed. Your new camera is supposed to be great in low light, so a slightly slower zoom is probably not going to limit your photography; the f/4 zooms are lighter yet and less expensive. I think you are likely to be happy with any of the Canon L series choices. Many who post here swear by their third-party lenses, especially the 150-600 zooms.

I had three primes with my film cameras (and finally, a zoom). It was always a frustration to need to change lenses when I needed a different perspective (especially where it was inconvenient to swap); it was also frustrating to settle for a picture that would have been better with a different focal length than I had. Now I have zooms that cover focal lengths out to 540mm (with the extender). I cannot imagine ever going to primes again--I take mostly family pictures or travel pictures, and the flexibility to frame or compose with a zoom is far more important to me than one or two stops of speed; if I move to more portrait photography or some other studio work, I might find a prime useful, but both the 24-70mm and the 70-200mm are great for portraits, too. The only problem is knowing which zoom to pick when touring a location for the first time (of course, you can just carry as many as you can handle). When trying to get wildlife, the longest lens is always the choice, if the light permits; Canon's super telephoto primes are quite heavy and expensive, and you should definitely try before you buy one of them (rental or try a friend's).

So, like the answers to most of the advice-seeking inquiries here. it depends...

I got my first DSLR in July, my first decent camera since film in the early '90s. I'm learning how to use it. I take a couple of flower pics and look at them, read some more of the manual. I decide to take some photos using the A and S settings. I set the camera to A - other settings are just how they came from the factory. I have my 70-300mm lens on and walk out into the bright sun, turn to my left and see a butterfly, click the button - and exposure #10 on my camera is this.


That's just awesome.

For reference, the aerial imaging camera I have has a max focal length of 210mm. That gets me 5cm pixels flying at 6,000' art a speed of about 300mph.

I'm a geospatial scientist and a technical advisor for some space imaging programs. Focal lengths are typically less than a few meters. What really drives things are the density of CCD's (charged couple devices) on the sensor and the aperture. For example, the aperture on Digital Globe's Worldview 4 is an amazing 1.1 meters. The lens (telescope) is definitely some fine glass, but it's all about packing in sensors and the speed of acquisition and data transmission.

I thought about this for a day before replying - it's a bit like choosing a favorite child - you love many, but for different reasons. I love the first because I was inspired. I was on assignment for the UN in Mozambique and out visiting a rural village. The poverty was extreme - people had to walk a kilometer to get to a well with clean water. I asked this woman if I could take her photo and this was her pose. She exudes defiance and strength in the face of tribulation and some immeasurable combination of satisfaction and pride that demanded my respect and admiration.

The next is the best photographic shot. One of those moments when the lighting and composition come together and you get the shot off and can't wait to see what it looks like off the camera. The latter is often somewhat of a letdown, but this one just works for me and I'm proud of it and glad to share it here. I was in Kruger National Park in South Africa.

The last represents a moment of triumph. I had a free day while working in Nepal and despite it being the rainy season - when I was told I would not see animals - I arranged for a walking tour through the jungle near India. It was a stifling 91 degrees, the air still, and light drizzle fell all day making conditions just miserable. After about 6 hours of leaches, a gallon of sweat, and getting soaked to the bone we came across this fellow going for a cooling swim. There are less than 1,000 one-horned rhinos left in the wild and I got to see this fellow and his mate. Shot this with the 100-400, but eventually swapped over to the 24-70 as he got within 40'. That's 1500 pounds of rhino swimming there. About died on the 4 hour hike back into "civilization", but I smiled the whole way.

It was a good year indeed and I am so very glad to be so blessed and fortunate.

Absolutely love it. We've figured out that that it's cheaper to vacation there than many other places domestically - $1,200 for the plane tickets, but then the lodging and all else is cheaper. We've also made friends with some of the park rangers and been cited in on the walks, the dawn and dusk drives, and some of the better (less crowded) blinds and overlooks. Just a great place!
