    You do yourself no favours postings such remarks. The Crew give up personal time to screen images. So everyone who genuinely uploads their images within the guidelines have to contend with waiting whilst we reject your “ double” uploads. Quite ridiculous!

    You obviously do not get english humour. The too much or too little contrast rejection has been a problem for a long time for many people - even using the histogram in Lightroom i still get that rejection. One of several reasons i dont bother uploading here very often

    I agree with that!

    I must say that the rejections by "too much or too little constrast" are the more frustrating, and the reason is: I received this rejection sometimes with shots that REALLY didn't have any issue with contrast, or are very borderline, while I see accepted pictures with very low contrast.

    Lets not forget: contrast is the "difference" (not the proper word, but my English is very poor, sorry) between the whites and the blacks, with a reference on the midtones. If what is meant to be white is pure white and what is meant to be black is pure black, then you have the perfect contrast, if the white is a little gray, OR/AND the blacks are a little gray, then you have low contrast issue. But of course it has to be balanced, in the opposite hand, if the clear areas have TOO MUCH white and the dark areas have TOO MUCH black, the mid tones will be going to be white or black and then you'll have high contrast.

    That's EXACTLY what is shown on the first post of this topic with that 747 example, which was PERFECTLY described using the histogram explaining what it says with that gaps and spikes.

    So, if it is so easy to identify the constrast issues, why are so many good photos rejected and so many photos with low contrast being accepted?

    I totally agree that there are some conditions when the picture will never be acceptable for JP or any other site that requests a higher quality standart. Specially when the problem is not only the overcast sky, but plus a umid or even dry haze in the air, like few fog or pollution. Or when the overcast is due to very heavy clouds that turns everything on ground too much dark, but I see rejected photos with very nice weather, just without the sun, but pictures with nice light, nice colors, nice exposure, nice contrast, nice dark areas, pure whites (not overexposed, not gray), etc... photos that the only difference to a nice sunny-blue_sky photo is the fact that there is no shadow on the ground and the sky is white not blue, but the lighting is fine.

    I'm having rejections that the histogram is pretty fine, not possible to say if it was rejected by too much or too little, so I agree with all the people who claims to separate it into two different rejections: "too much contrast" and "too little contrast".

    I have respect for the job that the screeners do voluntarily to make the site possible for us, but if the screener will reject the picture, then will have to search in the rejection reasons list and click on the one that aply, it doesn't add extra work for him/her!

    please check my thoughts on the attached photos bellow.

    Best regards

    I personally fail to see any contrast in the accepted photo.
    Both photos are borderline and can go either way. You just were less lucky.

    It would also save time if you actually read the whole thread..

    2.) Is the un-edited version image not editable at all because of the poor light?
    That is correct.

    Also, in the future, please start your own thread for any editing advice questions.

    Hi all,

    Most of my previous 15 images were rejected due to 'Too Much or Too Little Contrast' as a reason.

    One of the recent upload that was rejected for the very same reason is the shown below.

    1.) Does the edited image requires more or less contrast?

    2.) Is the un-edited version image not editable at all because of the poor light?

    Request you all to kindly help on this so that it will help me improve my editing.

    Awaiting a positive response.

    Thanks and Best Regards,

    I agree with the idea to find another rejection reason, because, when I see the contrast rejection the first thing that comes to my mind is Ok, I can fix it, but if the rejection is beyond of the contrast should be good idea add another rejection category, to avoid double upload.
    Hi Diego. I can say my thoughts on this.
    I believe that anyone is free to photograph an airplane in all weather conditions, but if you decide to upload them to share them here, I think it is right to stick to the community guidelines. I think this makes work more tidy and leaves no room for discussions on the quality of the shots.
    Excuse my bad English.

    Simply... when clouds are out stay at home or do not upload photos to JP. Personally i don't agree, but this is only my opinion.

    I agree that there needs to be some guidance from the screeners on contrast as it is majority of rejections. I have not changed my processing ways however I appear to be getting more contrast rejections as time goes on.

    - Contrast alone - Room to improvement
    - Contrast + quality - No Chance, one for the personal collection
    Great idea.

    I am relatively new around here and I like reading these constructive and useful threads. As a forum moderator elsewhere I am sympathetic to the role the screeners have. I am also painfully aware of the difficulties us novices have. For the more experienced ones here, a lot of the info and arguments posted are painfully obvious but for the novices they are not. For this reason, Alex’s suggestion, applicable to all photos, would greatly help as would including its definition in the upload guide.

    I for one, I am here to develop and have fun whilst I learn how to be a better photographer and meet new friends. I value detailed constructive feedback greatly and the difficulty for screeners is that the volume of pics they deal with means they cannot give detailed feedback -I wish I could sit with screeners and members and do a download of their expertise. As novices, we have to join the dots, figure out the bits in the middle and get better -that much is obvious and part of your own self learning. Fundamentally, knowing early on that a particular pic is not of the desired quality I consider extremely useful so I do not go wasting anyone’s time. Many of us will quickly learn, our skills will improve and we will hopefully avoid clogging up the system.

    With the pre-screening process now in place I wondered if there is an opportunity to limit the number of times a pic is re uploaded for screening. It could help reduce the size of the queue and perhaps encourage us all to be more selective about what we re upload.

    Best wishes to all.
