Adobe’s Lens Profile Corrections

Adobe’s lens profile corrections are simply amazing. Lens Corrections automate correction of standard lens distortions, including geometric distortion, chromatic aberration, and vignette. In addition to correcting lens distortions, this feature can also be used to adjust perspective and rotation.
 
Adobe provides support for a growing list of camera manufacturers, camera models, and lenses: Canon, Nikon, Pentax, Samsung, Schneider, Sigma, Sony, Tamron, and Zeiss.
Adobe Lens Profile Creator
If Adobe doesn’t supply a lens profile for your particular lens you have three choices.
First, you may be able to access a lens profile created by another user on the Adobe Lens Profile Creator forum. Find and share lens profiles at Adobe labs. Of course, these lens profiles will only be as good as the creators were diligent about creating them.
Second, you can visually adjust the parameters of an existing lens profile and save the new settings under a new name for future use. There’s plenty of room for user error with this method but it’s more efficient than creating manual corrections from scratch. Expect to check the results frequently when you apply these settings to different types of images.
Third, you can create your own custom lens profile with the free Adobe Lens Profile Creator utility. Download the Adobe Lens Profile Creator at Adobe Labs.Adobe Lens Profile Creator is a utility designed for photographers who want to create custom lens profiles for their own lenses. The process of creating a custom lens profile for your lens involves capturing a series of images of a printed checkerboard pattern with your specific camera and lens, converting that set of raw images into Digital Negative (DNG) file format (using the Camera Raw plug-in, Lightroom, or the free Adobe DNG Converter), and importing the raw DNG images (or JPEG/TIFF images when creating lens profiles for a non-raw workflow) into the Adobe Lens Profile Creator to generate a custom lens profile. If you create new lens profiles, you can share them with the rest of the user community on the Adobe Lens Profile Creator forums, publishing them directly from inside the Lens Profile Creator. These profiles will then be available via new versions of the Adobe Lens Profile Downloader. This is an extended and complex process few photographers will want to go through, but for those using unsupported cameras and lenses worth the time and effort in the long run.
Using Adobe’s Lens Profile Corrections
You can access Adobe’s Lens Corrections in three locations; Adobe Camera Raw, Lightroom 3, or Photoshop CS5’s Lens Correction filter. (Lens profile corrections were first introduced in Lightroom 3. To get Lens Profile Corrections in Adobe Camera Raw CS5, you need to download a version that has been updated after the release of Lightroom 3. You can download the latest free update at adobe.com.
It’s far less destructive to make these types of adjustments to Raw files during conversion rather than after conversion. It’s also more flexible. (Use a smart object and reaccess the controls any time by simply by double clicking the smart object.) However, if you want to apply Lens Corrections within Photoshop, after a file has been rasterized, you can use CS5’s updated Lens Correction filter.
In ACR and Lightroom, you’ll find two tabs under Lens Corrections; Profile and Manual.
Under Profile, click Enable Lens Profile Corrections to activate this feature. Using the EXIF data in your Raw file, the software will automatically select the Make (of your camera), Model (of your lens), and the Profile (for that lens). You can use the supplied lens profiles, download a custom profile made by another user, or create your own (manually or with Adobe’s Lens Profile Creator).
Checking Enable Lens Profile Corrections will also allow you to access three sliders –  Distortion, Chromatic Aberration, and Vignetting – for manually fine tuning the results. If you like the results of one correction but not another, you can decrease or increase the effects in one or more of the three fields.
Under Manual, you’ll find controls for visually creating your own lens profile corrections …

Navigating The Epson Printer Driver With Photoshop

Color - Management, Printing  Comment
0 Likes



Successfully managing color for digital printing requires that the color in an image file be converted from its device-neutral color space to a device-specific color space. (Typically this occurs by converting from Adobe RGB 1998 or Pro Photo RGB  to a device-specific color space defined by an ICC profile characterizing a specific combination of printer, ink, paper, and driver.)

Using Photoshop, you can either convert color in an image before you send it to a printer driver or after you send it to a printer driver.

Choose one method of color management – not two. Easily made, a classic mistake is using both. Double color management typically results in a print that is too light and magenta.

The Epson printer driver provides many ways to manage color conversions and get reasonably good color. Two methods offer the best results; the Photoshop route and the Epson route.
How do you choose either of these methods?

Let Photoshop’s Print window (under Color Handling) guide you – Let Photoshop Determine Colors and Let Printer Determine Colors. (While the principle is the same for most printers, interfaces will vary. Here’s information for the most current Epson interface.)

If you choose Let Photoshop Determine Colors under Color Handling, select a profile for Photoshop to make the conversion with (a paper/ink/driver specific profile not the interface default of Working RGB) under Printer Profile, choose a Rendering Intent of either Relative Colorimetric or Perceptual, and then click Print Settings. In the Print window choose the correct Printer and then change Copies and Pages to Print Settings. Select the correct Media Type, uncheck High Speed, and choose the highest printer resolution available. Finally, change Print Settings to Color Management and select Off (No Color Adjustment). The Photoshop route turns Photoshop’s color conversion on and turns the printer’s color conversion off.

The Photoshop route tends to hold slightly more saturation but it’s rendition of neutral colors and gray balance is usually not as good as the Epson route. The Photoshop route is the route to take when you want to use a custom profile. Use it if you are printing with either third-party inks or papers which require the use a custom profile to accurately describe the behavior of the alternate media.

If you choose Let Printer Determine Colors under Color Handling, choose a Rendering Intent of either Relative Colorimetric or Perceptual, and then click Print Settings. In the Print window choose the correct Printer. Change Copies and Pages to Print Settings to select the correct Media Type, uncheck High Speed, and choose the highest printer resolution available. Finally, change Print Settings to Color Management, choose EPSON Standard (sRGB) under Mode, and select Color Controls. The Epson route turns Photoshop’s color conversion off and turns the printer’s color conversion on.

The Epson route tends to deliver a significantly improved rendition of neutral colors and gray balance with slightly less saturation. Try it when printing neutral colors. Use the Epson driver’s Advanced B&W Photo feature for black and white images.

Each route works well. Each route yields slightly different results. Test them to see the differences. (Note that you cannot see the differences between printing routes when softproofing; you have to make physical proofs to see these differences. They can significant.)

Get This – Correct Color Management
Avoid This Double Color Managed
Is your print too light and magenta? Double color management. It’s a classic mistake. I sometimes make it myself when I’m working too fast. So that you know what to look for, I recommend that you make the mistake deliberately, once, and only once, if possible.
Don’t do this …

And this …

What’s the right solution?
Check your software (Photoshop or Lightroom) and printer software (Epson driver) settings, reset them, and print again. Choose one method of color management – not two.
