Printing images taken with SL2-S and 35MM Summicron ASPH in Cropped and 35mm Full Frame Modes

Ok, I've never really done anything like this before, so please be patient.

I was interested to know how the images taken with the SL2-S would look if I printed them. I am trying to figure out what the images would look like as I use larger and larger paper. For this attempt, I used my Summicron 35mm at f5.6 and about 1/60 shutter speed. The exif data says the aperture of the cropped image is at 6.8 but it was still 5.6. I noticed after taking the photos into Lightroom that the ISO changed, it was probably set on auto ISO.

In my first attempt, I actually printed the images and then took pictures of them on my iphone, but when I tried to upload them, the file sizes were too large. How ironic!

I tried to step back a bit when I took the photo in crop mode to approximate the size of the box. Obviously I guessed wrong.

In my next post, I will try to import a lower res picture of the actual prints that I put on my floor and took pictures of with my iphone.

As far as I am concerned, both are perfectly good in paper that is 8.5x11. Will try larger paper next.

Also, I would like to say there is an artistic reason why I chose a box as a subject, but really, it's just a box, and it was there, and I was taking a break from work, so I figured why not take a picture of this box in full frame and crop mode and share it with the nice folks at Leica Forum who always have such interesting comparisons! 🙂

One thing I can definitely appreciate now is how difficult it actually is to make these kind of comparisons and then share them!

Here are the iphone pictures of the actual prints that I made from the two files:

One thing that is clear is that you need to look at the colour-management of your workflow. Something needs recalibration or you have an Adobe RGB/sRGB mismatch on the way, as you have a blue/cyan cast and desaturation in the prints;  that is, if we can trust your smartphone. 

Next time. if you are testing, include a Greta/Macbeth target in the image.

The image on my monitor in Lightroom looks similar to the images as they were printed and pictures taken with the iphone (of course, the iphone turned increased the contrast substantially). The outlier, at least to my eye, is the jpg exported from Lightroom that I first uploaded. 

If you have any suggestions on how to check the color workflow, I would appreciate it! I am not very handy with this sort of thing. It was all I could do to get the images out of my camera and onto the forum post

In lightroom, under the print section, the color management says "Profile: managed by printer"

and in the print settings of lightroom for the printer, under color matching it says "EPSON color controls" where the other option is ColorSync.

Should one or the other of those be changed?

[augustwest100]

I went back to see what the JPG settings were in Lightroom when I exported those first ones, and it was set to sRGB. The other choices were AdobeRGB (1998), Display p3, and Pro Photo RGB. 

Which one should I choose in the export?

[jaapv]

LR is a case apart; it works in Prophoto and displays in sRGB.  The export  depends on the use. Most printers accept Adobe RGB, for the web you need sRGB. 

Basically your camera should be profiled, LR will take care of itself and your printer/paper combination must be calibrated or you can use a RIP. This assumes a calibrated wide-gamut monitor. 
In this case there is a vast difference between your images in the first and the second post. The first post ones are far better colour. I viewed them both on a calibrated Retina screen and a calibrated Eizo `CG one.

The Datacolor ebook (free) on this page gives a good simple rundown:

Thank you! I will give this a read!

 

BTW the original point of my post was really to show that the prints are still good at 8.5x11 in crop mode. Next, I will try 11x14. Color calibration aside, I was looking to see if one image looked more pixelated than the other. Is there a suggested resolution to print images at in terms of PPI?

[jaapv]

Depends - normally @ 240 - 300 PPI, but for larger prints you can get away with 150 PPI. But print size can be about as large as you want nowadays, uprezzing in Photoshop is quite good and there are excellent programs for the purpose.
