Photoshop Question

Here is an image taken with the Sony NEX-7 and Leitz APO-Telyt-R 1:3.4/180.

In the NEX-7 one can choose for Aspect Ratio either 3:2 or 16:9.

The following image was shot with an Aspect Ratio of 16:9,

corresponding to an image size of 6000x3376 pixel,

whereas the 3:2 ratio corresponds to 6000x4000.

 

If I open the .ARW image with Sony's Image Data Converter software, the image looks like this:

Obviously, the raw file contains all the 6000x4000 pixel data, but the ones lying outside the 16:9 Aspect Ratio area are darkened.

However, all 6000x4000 pixels can be processed and saved in an image, not darkened, or passed on to Photoshop.

 

Opening the .ARW image in Phase One's Capture One Pro 6, processing, and then passing on the image data to PS CS6 looks like this:

All 6000x4000 pixel are visible.

 

However, when I open the .ARW image directly with PS CS6's Adobe Camera Raw only 6000x3376 pixel are visible.

 

Here is my question:

 

Is there a way to open the .ARW file directly with PS CS6 and have all 6000x4000 pixel visible and available for processing?

i can't help with the photoshop question - no experience yet with 16:9 output from a nex.

 

i would like to ask if it wouldn't be useful to shoot using the 3:2 ratio and get all available pixels into the file, then, if desired, select a 16:9 set of pixels in photoshop?

I cannot answer your question, because I have different equipment.

But does it make sense to decide the aspect ratio, before the processing?

 

I believe, the Digilux-4 has a sensor with rounded corners. In that case you don't loose sensor area.

To be honest, I do the same by setting the ratio to 3:2, instead of the native 4:3 (APS-C).

Rick, Jan,

 

Thanks. Yes, of course, that's what I normally do. I have set the camera back to the 3:2 aspect ratio.

However, in this case I was trying things out to get a better understanding of how the NEX-7 works.

As I like that image, I am curious what I could do with it just in Adobe Camera Raw.

I don't know but I'd guess you'll just have to remove the cropping. Open the image in Camera Raw, select the Crop tool, right-click to call the Crop tool's context menu, and delete the crop.

 

Generally, it's a bad idea to shoot in another aspect ratio than the camera's native (which for the NEX-7 is 3:2).

Hi 01af,

Many thanks. Great suggestion. I use that feature all the time.

Doesn't seem to apply here. No crop to delete.

I agree.

 

Following is the image (6000x3376 reduced according to forum rules) I got from PS CS6.

I like the C1P6 processed image much better.

The colors seem much nicer to my eyes.

This is not correct. The native ratio for the Ricoh (APS-C) is 3:2. In pixels 4288 x 2848.

 

I am preparing for the solar eclipse. The sun is round, so a more quadratic ratio would not be bad. Especially, because my Telyt mirror 500mm crops to a 750mm tele.

But the technical data taught me, that 3:2 is the optimum.
