A fast-moving subject, or camera movement between the multiple exposures, will generate a "ghost" effect or a staggered-blur strobe effect due to the merged images not being identical. Unless the subject is static and the camera mounted on a tripod there may be a tradeoff between extended dynamic range and sharpness. Sudden changes in the lighting conditions (strobed LED light) can also interfere with the desired results, by producing one or more HDR layers that do have the luminosity expected by an automated HDR system, though one might still be able to produce a reasonable HDR image manually in software by rearranging the image layers to merge in order of their actual luminosity.

Because of the nonlinearity of some sensors image artifacts can be common.

Camera characteristics such as [[Gamma correction|gamma curves]], sensor resolution, noise, [[Photometry (optics)|photometric]] calibration and [[color calibration]] affect resulting high-dynamic-range images.<ref>{{cite book|last1=Sá|first1=Asla M.|url=https://books.google.com/books?id=mDsFgWPhWWYC|title=High Dynamic Range|last2=Carvalho|first2=Paulo Cezar|last3=Velho|first3=Luiz|date=2007|publisher=Focal Press|isbn=978-1-59829-562-7|page=11}}</ref>
