Regarding the tunnel pictures. I saw a bunch of articles about old subway tunnels needing maintenance so I thought this could be a good shot for such type of articles.
In addition to taking some photography courses, you should look at what other Stock Contributors are doing in your keyword categories to get a feel for what sells.
Thank you for the feedback, the links you provided are very helpful and I will keep them closeby and think more like a buyer in order to provide the most value.
According to you what pictures are needed except the ones pointed out in the trends or you can't tell me because of personal reasons?
Please do this; zoom your photos to between 100 and 200% to inspect them. They are all out of focus. You need to set the correct depth of field and to make sure they are in focus before snapping. To take landscapes need higher number F-stop than close-ups do.
The tunnel is way under exposed. There is too much of a black area where there are no details. If you zoom in on the black area you will notice it is not smooth black. It has some purple mixed in. That is color noise. The black should be black. The end of the tunnel is out of focus. The tunnel perspective is fine.
Out of focus
Too much of the road photo is out of focus (see above for reason). There is a white balance issue. The image is too blue (cool) - the green is not green, and it too is underexposed.
There is not a problem with the perspective. The horizon is based on the contour of the landscape. The road is level.
This photo seem to be noisy also, and there seem to be distorted pixels.
The field is completely out of focus. Judging from the plants the perspective is slightly out. However because there seem to be a slope and the horizon is so close to the edge of the frame. you'd need to use the tool in camera raw that makes both horizontal and vertical corrections.
Sorry, none of these can be resubmitted. You will need to take fresh photos.
A number of things could cause bad focus. If you use auto-focus, it could be that you are too close to your subject or do not understand how to know when your subject is in focus of the camera. Your camera usually come with a notification beep, or view indicator light that indicate when it is in focus. If you use a DSLR camera full manual mode, then you need to adjust the lens accordingly until the indicator light inside the view finder is steady, or until you see the subject in full view without blur and with sharp edges. To operate focus manually requires the use of a tripod to avoid movements. For landscape you need to capture focus about 1/3 from you. For object it is about a 1/2. The edges of your subjects must appear sharp. in the view finder, or on screen if you choose to use the camera monitor. For details about the different features of your camera and how they work look for your name and model camera online manual if you did not get one with your camera.
I will send you a direct message with your request.
Thank you for the article. It was very interesting and will serve as a good guide. Could you please send some more please?
To your question "How could these photos be used commercially?". Regarding the field I must have sumbitted it because of how good I felt at that moment in the field. Therefore I have mistaken sentimental for commercial value in that case.
Regarding the tunnel pictures. I saw a bunch of articles about old subway tunnels needing maintenance so I thought this could be a good shot for such type of articles. Perhaps the mistake in this case was that I did not convey such uses.
Could you post som more reading or tips regarding composition and your thought process about how something can be commercially viable please?
You may find that trying to improve your skills by sending to a commercial service which demands the best possible professional work is a difficult or frustrating way to learn. There are many kinds of technical issues, some of them need a trained eye and close magnification. Some are simple, and some are art ("composition").
Tunnel and field are not level, woods may not be level. This is specifically shown as a fault in Adobe's documentation.
The tunnel is too dark. I know it's a dark tunnel, but the contrasting parts need to be sharp, clear and well lit. Also the large element at the left of the tunnel is hard to understand.
