Also, be aware of diffraction.
In the beginning, i had many rejections because I was shooting with small apertures such as F16 and F22 in an attempt to get large depth of field. At these smaller apertures, diffraction can become an issue and be mistaken for lack of sharpness.
Every lens has a 'sweet spot', a F-stop where sharpness is at it's maximum. For a lot of lenses it's around F5.6-F8. This will vary somewhat between lenses and camera sensor format.

Yeah Daddiomanottawa. I never shoot over f11 to be honnest, but I would like to explore.
I think that apperture must to be used as an artistic resource instead just as a light compensation.
I like to use wide apperture (like 2.8) because i like to separate main object to the background. But sometimes I like to use F8 as well.
Well, one thing is a sure, to have a photo on a stock, this must have quality, but it doesnt mean it must be PERFECT image as well. Just good is enough, but as more quality is better of course.

f/22?!
That's a total overkill in landscape photography. That kind of aperture is needed only if you need to have an apple in focus and fill the frame when you have only a 50mm lens.

Theoretically, a cropped sensor attains maximum sharpness at f/6.3 and the quality degrades beyond that. But it isn't really noticeable until you are as small as f/11. After f/13...better to just not go beyond that.
A full frame sensor can give you good sharpness at even smaller apertures.

Hi Robinstockphotos. I use only f22 or something if I want to make waterfall smooth effect and I don´t have a dark filter.
So you say that the maximum sharpenes is at f/6.3 for croped sensor? Hummm, intersting. Do this work if I use any lenses? I use mostly a sigma 70-200mm
Thanks for reading and write. :)

Indeed, beware of too small aperture like F18 or worse F22, or the DIFFRACTION will occur lowering your overall sharpness. Around F8-F11you will always find your sharper pictures, depending on the lens.

Thanks for the complement @Spat78
I am still learning all that, but after learned some basis I decided write this article because I know that many people are making a lot of efforts on many ways and I think it should be interesting that people knew how to make a sharp image because it's what they want when they buy a DSLR. But many buy it and keep shooting like point and shoot and get a few disapointed. I think that they can improve a lot if they follow some instructions like this one you said now.

Novices beware, while much of what Maxsp is right, I can not agree with all of it.
1-yes
2-no, tripod? Monopod? VR/IS? Studio strobes? Too simplistic rule
3-no, 70-200 only if shoot distant subjects, no use for architecture and of limited use in a small studio
4- just wrong, buy a quality 70-200 and try again, focal length only affects quality with cheap kit
5-no, noise is a function of the camera/light not the lens
6-no, only if your subject is rock solid static.
7-no, wide aperture limits depth of field, it does not make a picture blurry, wide aperture and selective focus is a very effective tool in stock photography, learn to use your kit creatively
8-no, modern auto focus is very effective, use the centre point if necessary. Manual focus requires a special focusing screen which is not fitted to most DSLRs, check the screens in old manual focus film cameras.
9-only on cheap lens does this make a significant difference, professional lenses from Nikon/ Canon/ Sony are very good throughout their range.
10-answer as 9 above
11-no, all depends on what you are shooting, Sigma are cheaper for a reason, check out the used market and ask yourself why folk are prepared to pay more for main brand kit?
12-lenses are more important than body for quality of image.
13-answer as 12 above
14-not always true, crop cameras produce very high quality pictures
15-if it suit your work flow and time is on your side
16-yes
17-Full Photoshop is nice but far from necessary, elements or paint shop pro do a very good job, plenty good enough for basic photography processing.
18-yes
19-yes
20-no, take plenty yes, but before you take the picture think about what you are seeing in the view finder, if you cannot see a picture that you know is going to make you $$$ then don't take it! take lots but try to make every picture a quality one
21-yes, I have just done so

Sorry not to agree with all your post Maxsp, but they are just a few words from an old man who has been taking picture since the 1970's

All the best
