Rules for Posting Guides on Our Community
1. Defining a Guide Guides are comprehensive reference materials, how-tos, or comparison tables. A guide must be well-organized both in content and layout. Information should be easily accessible without unnecessary navigation. Guides can include flowcharts, step-by-step instructions, or visual references that compare different elements side by side.
2. Infographic Guidelines Infographics are permitted if they are educational and informative. They should aim to convey complex information visually and clearly. However, infographics that primarily serve as visual essays without structured guidance will be subject to removal.
3. Grey Area Moderators may use discretion when deciding to remove posts. If in doubt, message us or use downvotes for content you find inappropriate.
4. Source Attribution If you know the original source of a guide, share it in the comments to credit the creators.
5. Diverse Content To keep our community engaging, avoid saturating the feed with similar topics. Excessive posts on a single topic may be moderated to maintain diversity.
6. Verify in Comments Always check the comments for additional insights or corrections. Moderators rely on community expertise for accuracy.

Ppi is pixels per inch so I’d guess the measurements are in football fields or busses or whatever it is the Americans use at the moment to avoid the metric system
what units were used for the print size?
Inches
Yuck. When will those eternally backwards people learn proper systems of measure?
We'll do that when metric learns how to have more than 4 factors from one unit to the next higher one.
Ew the x-axis shows no unit and the y-axis shows the unit in the tick marks?
I see Print size in X, Camera Resolution is Y, PPI in the boxes.
Print size in what unit? Centimeters, inch, bananas?
Inches. Obvious to those that are used to seeing frame sizes in that.
Which probably limits the selection to Americans.
300dpi is the industry standard baseline for printing, 150dpi is not "excellent" it's barely usable without pixelation being visible in the print.
Viewing distance is a big factor with regards to the acceptable resolution, which is ignored here.
The film data is way over ambitious. I don't think blowing a 35mm negative up to 16x20 is "superb."
A 50 ISO is great a 800 ISO is shite.
Yeah, all of these values are going to depend on a low ISO. You can have 60+ MP but if you're shooting at 3200 ISO it's gonna look shit blown up, less than say 30MP but still your not going to get these numbers.
I do wish smart phone manufacturers were competing to increase the MPs in the cameras because I'd love to be able to get some large prints out of the photos I take. But they just wouldn't look as sharp as I'd want them.
And no, I'm not buying a dedicated camera to carry around because I'm not an actual photographer, just a parent taking a bunch of photos of his kids.
Just adding megapixels doesn't give you more resolution, you also need a lens that can resolve the detail which often means a bigger lens.
Cell phone MP can be fake anyway, I have a 48MP one but the fine print is the extra MP are interpolated based on the neighbours so it is basically shitty MP that is algorithmically cleaned up for higher resolution.
This chart is very difficult to read for those with color deficiency - about 8% of men. Good and Fair are nearly the same, as well as Better and Superb. It would have been really easy to just use 5 shades of gray, or 5 colors that are distinguishable in greyscale.
