    I almost never use the histogram to check contrast. For screening purposes, histogram better suited for checking exposure than contrast since the histogram refers to the whole frame rather than just the subject we are concerned about, the aircraft. As such, if the whole frame is well balanced, but there is poor light on the aircraft itself, this will not be apparent by looking at the histogram.

    In your specific image, you've got some rather harsh light coming off the aircraft itself which you've tried to compensate for by bringing down the exposure which is not a great combination. Histogram is not going to tell you that, in fact as your post highlights, the histogram in this case is going to show that the frame overall is well balanced.
    Thank you for the detailed explanation. This will help me understand contrast better moving forward if and or when there might be poor/harsh lighting on the aircraft. I will learn to rely less on the histogram for contrast in cases like these. Thanks again for explaining this from a screeners perspective

    • Hello Dana, and other pre-screening screeners, I could really use your assistance with this one. One of the main issues that I think might be an issue is the horizon and would like your input on the matter. Along with the horizon, could you tell me if my contrast, exposure and sharpness are sufficient, especially at 1920px. Thank you very much in advance

        Would be rejected for horizon and soft/heathazed. Quality is not there for 1920pix.

          Thank you for the feedback Dana, in terms of suggested rotation for horizon would you suggest CW or CCW?

            At least 0.5 degrees CW.

            • With this photo, I am looking for feedback on whether the horizon is level and if there is any prominent haze that will render this photo rejected. Thank you in advance.

                Horizon looks ok to me. Haze is somewhat noticeable.

                • For this photo, are there any issues that you see with softness/haze as well as contrast and exposure? Also, is framing sufficient? Thank you

                    Borderline for haze, yes. Can see it a bit on the nose, and for sure on the mlg.

                    • So this is my first attempt at photography from an aircraft and I would like to know if this photo meets the standards for JP for an airport photo. In terms of exposure, sharpness, and contrast, does this meet the standards? Also, would there be an issue with color/hue? Thank you in advance

                        I'd say probably not: too many soft spots, and the contrast is not great, though the latter is not really your fault.

                        • Hello forum crew. I was going through some photos of mine and was curious as to why this particular photo has been excluded from FR24?

                            I wasn't involved, but most likely because it is too dark. FR24 prefers the whole aircraft/livery to be seen easily.

                              Ah, okay. Understandable. I was just looking for an explanation. Thank you Dana

                              • So I went out night spotting yesterday evening and I was looking to get some feedback on these two photos.

                                1) with this photo, would this be an airport overview photo or would I use the aircraft (N148UP) as my upload process. Would the contrast and color be sufficient and are there any issues with exposure and horizon. If deemed airport overview, which category would you recommend for upload?

                                2) with this photo I had one similar get accepted where it was stated that it could be considered backlit. Will this deem the photo as unacceptable? if not, are there any issues with color, contrast and exposure?

                                3) Any issues with exposure and contrast?
