1MB Upload Limit: A Bit Harsh?

Thu Oct 23, 2008 6:43 am

I just took a trip up through North Florida and Alabama. I changed a few settings on my camera, and am now shooting in all RAW instead of before. After getting all my pictures on my computer at home, I'm having a very tough time getting them down to below 1mb for upload. Its a bit confusing, as I'm using the same process I've used to get some 60 or so other pictures of mine accepted.

1060x795
400 Pixel Per Inch

suddenly most of my photos are way over a 1MB limit after processing in photoshop, even after resizing them down to 1020x765 and 200 PPI.

I'm curious as to two things: With the newer Higher resolution cameras is having such a small upload limit a bit harsh?

And What gives with my weird conundrum of not getting photos below 1mb?

At 1024 wide you should have no problems staying under 1mb

300 ppi is enough.

Convert to jpg, crop, downsize in PS, then sharpen. If still over 1mb, save at quality 11 instead of 12.

Not really....hardly any of my photos, shot with a 40D, exceed the 1MB limit, even when saved in PS at a maximum. The viewer won't notice a difference between a shot saved at 11 or 12.

So, in order to answer the question. No the limit is fine as it is!

Whappeh, I think you are getting confused with resolution. PPI only applies when you are printing. If you have an image at physical size of 1024x683 then you have 699392 pixels in your image. If you change your print size and keep the number of pixels the same you either raise or lower the resolution.

So for internet usage only look at the actual number of pixels resolution means nothing.

I size my images 1200x800 (960000px) and never have a problem getting under the 1Mb limit.

Depends on the nature of image too: photos with a lot of blue sky tend to "weight" a lot less then, for example, airport shots with busy backgrounds.
I personally would like to see size limit raised - at least by a little bit.

Don't sharpen the busy backgrounds... helps a bit.

It also depends on how you process your photos too. For example, I prefer to directly crop my images to the acceptable size limits to avoid the degrading effects that resizing has on image quality. For standard 1024x683 I easily get under the 1MB limit. However for this shot I stcropped to 1000x1125 and it took me several attempts at cropping to get it to the 1MB limit.

Having a little bit more flexbility to upload larger files would make the effort a little easier, but I understand there are reasons for the 1MB limit.

I've always been told cropping too much does more damage than resizing. So for example, for a full body shot, normally full frame at 200MM, at 3888 x 2592 (10.1MP, 3:2 ratio), you would have to take that shot at 52MM to crop in to 1024x682 to achieve the same result as shooting at 200MM and resizing to 1024.

Am I missing something?

I'm shooting with a Canon EOS 20D (1.6 crop) with a 100-400 Canon Lense. My experience (which may not be typical) is that directly cropping to size and eliminating the step of resizing spares me some of the problems that hit quality like jaggies and such (although still get the damn things when I apply too much USM.) I've never processed a full-frame photo this way.

My camera has a 1.6x crop factor also, but, I have always read (and experienced myself) that directly resizing improves actual quality, rather than cropping severly. If you have a slight out of focus or blurry image, and you crop in alot, you will still have a blurry image, but when you resize, some blurryness is taken away, thus improving quality, with a 100-400 L you should have absolutely no problem losing quality by resizing directly. You will get a good amount of jaggies if you resize to a crop ratio unequal to the original (i.e. 3:2 to 4:3).

When I resize an image from 3888 to 1024, I see image quality increase, blurryness decrease, and no jaggies (maybe a few spots here and there, but nothing severe enough to get a shot rejected).
