It's just customary to upload a full-frame and 100% crop for the archive. Gives us pixel peepers an idea as to how the lens performs.

Whats a fullfram picture?
Is that the RAW or a Jpeg in original resolution?
I never made a 100 crop and saved it to an uploadable size, how do i do this best?

Tony-S · 17th of December 2007 (Mon)

Full-frame is the image reduced to 800 pixels on the long axis and a 100% crop is an 800 pixel by 800 px crop of the image's focus point. These are the max resolution allowed for images uploaded to the Forums. Save them as JPEGs and make sure the file sizes of each is less than 100 kb in size. See this example. Your image editor should allow this.

Malk · 17th of December 2007 (Mon)

Im sorry for the many questions, but im very new to this.
When you say 800 pixels on the long axis do you mean number X 800 pixels, or 800 X number?
The reason im asking is because the 2 pictures i added are both 800 pixels wide

Im also having trouble finding a guide to making a 100% crop in photoshop or any of the Canon editing tools :/
When making a 800x800 crop in DPP and save the file its still 3888x2592, do i just resize that to 800x800?

Click on the Crop tool in PS. In the pulldown of the top tool menu, choose 'Fixed Size'. In the two boxes that appear in the tool bar at the top, type '800 px' in each for width and height. Click on your image and an 800 x 800 pixel box will appear. Move it to where you want, then crop it. That's an 800x800 pixel crop. Save as a jpeg less than 100 kb in size and you're ready to upload.

Resize so that the 3888 is 800 px, then just make sure aspect is preserved and the 2592 will automatically be calculated. That would be a full-frame crop.

We cannot tell you from your post since we did not do the crop. It may be 800 x 800, but if you resized it, all bets are off.
