Thank you

Yes, in lightroom I use 100% quality and 300dpi when exporting jpegs. I wasn't aware the Adobe RGB color space was an option under jpeg as switching from tiff to jpeg, it defaults to the sRGB color space, so I suspect that will affect size as well. This is a huge learning curve, so thanks for your input.

Thanks for the good information.

Actually I have learned in life people will mislead you to increase a profit, therefore my inquiry is to help me make an intelligent decision as to which print lab to use. I seriously doubt all print labs use the same formats for printing as you seem to imply. Your response is ridiculous and condescending. Please move on from any of my future posts as your replies are not needed or wanted. Thank you.

I just learned something. I did not know lightroom gave the option of exporting jpeg files as Adobe RGB because it automatically switches it to sRGB when choosing jpeg. So I checked and found you can still choose Adobe color space. That should increase my file size significantly. Thanks much.

Not sure what I'm doing wrong because my raw files are about 23mb which is what I use for editing. I can't find any higher resolution setting in jpeg when exporting than what I'm using. What do you use to edit your files? Thanks for your reply.

If I replied to the wrong post here about attitudes, my appologies.

I'm trying to learn, I don't need attitudes like yours for that.

I am soon to a point of wanting to get some large wall prints made. Most print labs I have checked want Jpeg files in an sRGB 8 bit color space. I understand this is fine for smaller prints or web viewing, but I am concerned about the quality of a larger print, say a 20"x 40" for example. When exporting from lightroom, my tiff files run approximately 90-100mb in Adobe 1998 color space. The highest quality jpeg I can export usually runs about 5-6mb in the sRGB color space. These labs claim the eye can't see the difference in the prints, but I'm very skeptical of that. Adobe also has Prophoto RGB which I haven't used. Can anyone enlighten me at all on this topic, and possibly a print lab they would recommend? Also, it will be mostly landscape/nature type pics I will be working with. Thanks in advance for any good advice I get.

Ok, thanks

Early morning Bastrop State Park

Took the clouds out and toned it down. Am learning, again, thanks for all the feedback. That's why I post here, to get honest feedback so I can learn. I have a hard time not "cooking" these pics.

Thank you

This one is with the temp slider towards cooler which enhances the blues a little more, don't think it's too unnatural?
