Ok If you say so, but microscopic it is not the diference as master yoda would say, take for example print size if you try to enlarge something that was rendered at 1900 x the image will be blurry even using photoshop jpeg save as max quality! Make the experience take one of your pieces and enlarge it to the res i refered to you and you will see, it will get blurry. But the resolution you use is greater than any desktop resolutions most ppl use so no harm done .
In windows 7 you have to resise images to match desktop resolution to use them as wallpaper or it will get artifacts and quality degradation, so it`s always better to render high and being able to reduce than render smal and not being able to enlarge. that`s just my opinion!
I just love your gallery! you deserve some serious compliments for it!!!!
I understand the whole print/resolution idea, and I have rendered things at high resolution, I just choose to render at 1280 X 1024 for myself(and others of course), and 1920 X 1200 for others with widescreens. I don't sell prints anyway, so it's good enough for me. Thanks so much for the compliment, you have an awesome gallery yourself, and I'll be strolling through there in a bit!
