Workflow to convert for web
« on: July 20, 2014, 09:34:44 pm »

I shoot only in Raw.
All my edits are done in a ProPhoto RGB environment. Once the files are done I save them as TIFF, no compression.

I don't consider it finish unless a print looks as good as my calibrated monitor.

Seems like my success is a bit of hit and miss when I convert a finished photo for posting a photo I have already printed and edited to look like I want it to in the screen or in paper. Not always, just often enough to make it a pain.

I have uploaded a couple of dozen finished pictures to the Behance portfolio that Adobe includes in the Photoshop subscription, 5 or 6 of those pictures don't look good, the rest are perfect renditions.     https://www.behance.net/hugoperonace

In one case the colors look a bit muted, in other its a tiny bit of a color cast.

I imagine the problem is in one of the steps of the conversion to jpeg.

Anyone here has a detailed step by step workflow to convert a finished photo to a jpeg file ready for upload? Or a link to a good description of such workflow.

Thanks

Hugo

What is your workflow for conversion for web so far? Are you converting to sRGB space, as you should?

jpeg is a file type, basically about compression.  While it is limited in some respects in color, problems in color you describe are about proper conversion to sRGB, and no matter what you do the result will rarely look like your managed workflow.  As photographers we set up our displays to simulate what we will get when printing.  As such the display cannot show what the average viewer will see.

but then what display would?  the entire thing is completely hit and miss ... since the monitors of the those viewing the images vary wildly, and you don't even know if the OS/browser is color managed.

I have a few personal opinions,( which most don't share), I think that almost every display out there is much brighter than mine, and is also cooler than mine.  So I have a second display calibrated for sRGB, 160 cd/m2 and 6500k WP.  I try to make sure my web images are slightly darker and slightly warmer, and they look pretty good on both my calibrated display and my web display.

Not sure which ones don't look good to you.  But to me your photos are beautiful regardless of what you think about some of them.

Thanks Alan for your kind words

My workflow:
From a Tiff file, layered and living happily as Pro Photo Rgb
Flatten all layers
Fit image to a constrain size, usually 1000x1000
Convert to srgb profile
Convert mode to 8 bit
Sharpen
Export

My problem is not the luminosity, rather the slight shifting of hues and a bit of a loss in contrast.
I suspect somewhere in the trip from one color space to the other, some of the files, take a good beating and don't show as the original before conversion.

In the folder of my website named The Other Place, all underwater pictures.

The 3rd, 5th and last pictures have a color shift, greenish, and lost the "pop".
The other pictures show well

I have soft proofed the images before converting to sRGB?

When I convert the third one back to ProPhotoRGB, add a some saturation, then soft proof as sRGB, most of the image is out of gamut.

Thanks Brian
That could be it, I normally don't soft proof the pictures because I have the whole workflow as an action.
Just click play and grab them for upload
And srgb is a smaller color space than Prophoto isn't?
;D
You are a genius!

Huguito,

Have you ever thought of producing your web galleries directly from the raw files in Lightroom? The LR Web Module does a great job and it's a seamless workflow, under the hood once you set several basic parameters.

I have never tried doing it out of Lightroom, actually I had barely used Lightroom at all.
Got used to Camera raw and Photoshop, is hard to break old habits.

Lightroom is a very easy habit to get into, and once you get into it, (a) you'll wonder why you never focused on it before, and (b) it will become an even more difficult habit to break :-)

Give it a try - everything to gain and nothing to lose. You can always go back to the more difficult old ways if it doesn't float your boat.

Hi Mark
Other than the Scott Kelby Lightroom book, can you think of anything else comprehensive enough to get a good basic handle on the basic functions of the software?

Hujuito,

By far, (in my opinion) the best and most comprehensive documentation of every corner of this application is Martin Evening's Lightroom 5 book Lightroom 5. While I work in this application day-in day-out, that book is by my desk within reach all the time. It is highly unusual that I fail to find in there anything I need to know, and very well explained.

Hi Mark

IMHO, most of the books I've got on the subject are far superior to Kelby's! Martin's of course, then the work by Mr. Schewe and if you prefer video's, George Jardine's are the best resources around! But totally opposite of Kelby's "here's how to do something in 7 steps and I'll dumb it down for you" approach. George's work is very comprehensiveve, through and deep! For example, here's a superb example of a free video he did on color to B&W conversions in various products including LR:
