90 % of the photographs on this website were taken with a very low-end camera, the Kodak Z740 :
The problem I encountered was that the definition was not very good so I resampled each picture as follows through Photoshop .
You have the procedure well explained by clicking on this link : Adobe Help , it may help you too .
Thanks to adobe for their illustration :)
My pictures were in low resolution so I doubled the size of each picture and for a better print , I changed the resolution of 72 pixels per inch to 300 ppp by checking " Resample Picture " on Photoshop . I tested an enlargement 40 x 60 cm as in the picture below and the result is more than satisfactory :
Zoom in :
Meanwhile , I bought a new camera , the Nikon D850 :
Since , no more problem about resolution , now I have more than 45 mega pixel :D
My lens is a Sigma 50 mm F1.4 DG HSM Art
Pictures were calibrated with Lightroom software .
I also used Photoshop to resize some pictures for example .
I work with a calibrated display : BenQ SW2700PT
My calibration probe i1 Display Pro de X-Rite
It is important to work with a calibrated display .
In this regard , you may find color differences if you look at my pictures with a non-calibrated display such as laptops or other computers . Indeed , according to the manufacturers or the retailers , the commercial screens do not all have the same color temperature , the same luminance . Some may have a red , blue or green dominant while being far too bright .
My display has these values below :
Luminance : 120 cd/m²
Color temperature : 6500 K
