Sinar e54LV samples at all ISOs

[Graham Mitchell]

Someone ('wildstork') requested this via email but I may as well share it with everyone here.

What was requested was full resolution samples at various ISOs so I went out and took a very boring photo with no artistic merit whatsoever  What is does have is lots of detail, dynamic range and colour.

I took the same shot at all ISOs, changing only the shutter speed and ISO setting.

Then I pulled all the files into Photoshop and layered them on top of each other, with the layer names showing you which layer is which ISO setting. You can therefore zoom in and flick between layers to see the difference up close.

These files are UNSHARPENED and there is NO NOISE REDUCTION.

The member who contacted me offline wanted to do some test prints, so you are all hereby permitted to download, print, or do anything else to this image.

The file is a 511 MB Photoshop file, so I had to split it into 6 smaller pieces in order to host it. These are in the form of a ZIP archive.

Ok, a Mac user is reporting difficulties offline, so here is a guide to restoring the file.

PC users: use Winzip, for example. Free trial version will work. This was utility used to create the plit archive.

Mac (Intel) users: Intel Mac users with Parallels can also run Winzip, or see Mac PPC solution

Mac (PPC) users:

1. Change all the .z01, .z02, etc. file extensions to .001, .002, etc.

2. Change the file extension of the .zip file to .00X (X= the last numeric file extension from the .001, .002, etc. files + 1). In this example, the zip file extension will be changed to .006

3. Join all segments with "MacHacha". (Drag the .001 file onto the MacHacha icon)

4. Change the name of the file produced by "MacHacha" by adding the extension .zip .

5. Unzip the this new zip file with "The Unarchiver". (Drag the zip file you just renamed onto the Unarchiver icon).

I just tested this solution and it works.

If anyone knows an easier Mac OSX solution to restoring a file from a split zip archive, please share! (Next time I will use split RAR instead of ZIP - there is a much easier solution for Mac users).

ok, by popular demand, the DNG files:

In case some Mac users are not aware, if you want to download the files in the original post, before clicking on "Click here to start download" hold the CTRL key....and then select "Download Linked File As........"

Or you can just hold down the "alt" key when you press the download link (at least in 10.5.x).

Usually if I need to join split ZIP files (or any other kind of split file on my Mac, you run "Terminal" to get a shell prompt (scary for some I guess). Assuming you downloaded those files into the Pictures folder, at the "$" prompt, type:

cd Pictures

and press the "return" key.

Then type

cat file1.z01 file2.z02 file3.z03 ... filen.znn >really_big_zip.zip

and press the "return" key. When that's done, quit the "Terminal" program, find the "Pictures" folder in the Finder and double click on it to expand. No need to download additional software from the Internet or install anything.

This is what it looks like on my Mac:
