Can we use transforms for basic rules? Like perspective (to fix converging lines)? rotate to align the horizon?

Under the Basic rules you can rotate, but you can't use any of the transform tools (Perspective, Skew, etc.) -- sorry. You can use them to a limited extent under the Advanced rules, but basically to make the photo look more realistic, not to introduce "artistic" effects.

I would think so, as long as it is applied to the whole image.

But I'm a newbie, so....

[quote]"Post-shot Adjustments may be made to your image in a photo editing program, so long as the modification is applied to the whole image. This includes levels, conversion to black and white, hue/saturation, sizing/rotating, curves and cropping..."[/quote]

not sure about perspective -- although I believe you would have to make a selection to do it...and you aren't allowed to make a selection except to make a border...

Sorry...I was too busy looking for the Schultz picture to bother with checking on the facts...

nah...I was quoting and researching...I just need to multitask more. I think I used one window for all of it. If I had some more RAM I could have maybe used 5 windows and two keyboards then I could have beat you.

I've just spent almost two hours getting a reliable browser connection -- I got back online just in time. I don't think a second browser window takes significant RAM or resources. One of the most common strategies of people with slower machines and connections is to always have two windows open when voting, so one photo downloads while you study the other.

But if he checked a fact or two he'd know something ... and blow the schtick I guess ...

I just re-read the rules again, i don't see that transforms are prohibited....

they are though, because you have to make a selection (for a purpose other than to add a border) to do that and distort pixels not as a whole.
02/11/2005 12:21:51 AM · #13
But if you're drawing a box around the entire image....is that really a 'selection'?
02/11/2005 12:24:37 AM · #14
call it what you want, I don't know and don't pretend to know...i was just reading off the rules.

In the basic rules: Additionally, the use of any type of selection tool is prohibited except to select a non-feathered, non-anti-aliased rectangular area for cropping.

Can't do a perspective correction without making a selection first. In any case, a perspective correction involves actually moving pixels within the image, and that's not allowed in basic.

hrmm...which brings up a good question...if rotating is legal, but selecting for any reason other than to make a border isn't, how do you rotate without making a selection?
02/11/2005 12:41:18 AM · #20
Right, rotation is fine. And cropping. They go together, lotta times :-)

Because rotating is expressly permitted.

So using Photo Shop Distort and then lens corrections straighten verticle lines when using a wide angle lens is not allowed? With this there is no selection made and the entire photo is used.
