A digital image has no physical size, it has a resolution. A Nikon D500 has a 20.9 megapixel sensor. An uncropped image from that camera is 3840x2160 pixels. If you have a standard wide monitor that’s 1920 pixels wide that image, displayed at full screen, is actually compressed. At full 1:1 resolution only a little more than 1/4th of the image would fit. It’s generally accepted that for an 8x10 print or smaller you want 300 pixels per inch. So for a landscape print of 8x10 you’d want an image that was at least 3000 pixels by 2400 pixels, 4x6 you’d need 1800x1200. So know you might think, “how can I print a 16x20 from my D500? I need an image that’s 6000x4800”. Well that’s where viewing distance comes in. You’re not gonna be viewing a 16x20 at the same distance that you view an 8x10 or smaller. The farther away the viewing distance is the less DPI you need. Billboards are usually printed at only 15 DPI.

That is my thought also. That is why I was confused that the original post was for a 4 x 6 inch photo. I could submit a photo with 16 pixels by 24 pixels and still meet the criteria. Be a lousy picture, but still meet the criteria.

The requirement of minimum 4x6 isn't correct but if the OP wants to submit his picture he can simply ignore it.

“The Virginia Dept of Wildlife Resources publishes an annual issue depicting flora and fauna native to the Commonwealth of Virginia. They accept pictures for inclusion and designate the size of the images submitted for the article as a minimum of 4" X 6" ” Trapper please provide a link to the VA DWR source which validates this inference. Thanks!

Here are VA DWR’s actual publication requirements:
Quoted verbatim from the "VA DWR Print and Digital Publication Guideline"

Guidelines for Freelance Photographers
Technical Requirements:

Digital: RAW of TIFF files preferred, though JPEG can be submitted. Shoot at the highest resolution possible (300 dpi minimum). Send original, unaltered files (do not re-size).

All digital photographs must be true to the original images and free of digital alterations, except minor cropping.

Digital files must include metadata to include photographer name and contact information and location of image taken.

Source: https://dwr.virginia.gov/wp-content/uploads/media/writers-photographers-guidelines.pdf

Trapper there are DWR contact email addresses included in this document. I strongly recommend using them for your query. I do not consider UHH as a reliable source for publication related information.

The responses you’ve received thus far tend to corroborate this inference.

Wishing you much success on your endeavor Trapper albeit at best you can only expect $250 for a Calendar Cover and even less ($200) for their publication covers. This is the compelling reason I no longer bother with magazine submissions. Commercial Portraiture reliably pays the bills and likely will remain a viable revenue stream moving forward.

Cheers! Thomas

I am familiar with manipulating the size of images using pixel count but have no idea of how to convert inches to pixels. All of the images in my computer are of course identified in part by pixel size, not inches. Is there a formula for converting images from pixels to inches and vice-versa?

As Thomas pointed out, they will take raw or Tiff files. They, or no one, will ever get my negative (raw). Tiff maybe, but since the accept jpeg, that's what I would do. Jmo

Their requirements raise many questions. They require 300 dpi. That’s completely meaningless. When submitting digital images there is no such as dpi. They say no digital processing except minor cropping and they’ll accept JPEG but prefer raw or TIFF. Raw images aren’t a finished image and aren’t designed for optimal viewing. Do they intend to process our images as they see fit? I guess for people that submit it’s more about the cachet of having their work published more than it is the money. Yeah but if I can’t process it as to my vision then it’s not totally my work.

That's a poorly worded requirement for digital images, but to hit the minimum, assure your image is cropped in a 2x3 aspect ratio and at least 1200x1800 pixels. If you think you can get a full-screen presentation of your images, online, maintain the 2x3 aspect and use 2048px as the long-side pixel resolution. Or even, 2000x3000px.


I don't believe that the aspect ratio is of any importance. The image just needs to be larger than 4"x6".

In ACR I edit raw images and save the edited version in raw format.

Below is a screen capture of the technical requirements of the Photography/Artwork Submission, assuming the Thomas link was to the proper site and requirements. Our OP seems to have invented the 4x6 requirement as that does not occur anywhere in the PDF. If they had stated such an aspect, cropping to 2x3 would have been relevant.

But when in comes to editing and 'saving' to RAW in Adobe Camera RAW, I need to break it to you: no you are not saving to the RAW file. The only software that 'writes' into an original RAW file might be the original camera manufacturer's software. All other software that 'save' RAW edits do that via a XMP sidecar file or a 3rd party wrapper such as a DNG or PSD. Neither of these are accurately described as 'saving' the edits to a raw format.

Coming back to the requirements, the first bullet saying a "RAW of TIFF" is nonsense. A request for 300 dpi is nonsense. A digital scan of original artwork at 360 dpi and no smaller than 8x10in is nonsense. The best one should do is deliver a high-resolution JPEG in the sRGB colorspace, with a minimum of cloning / masking edits to the original capture. Then, hope they select that entry and the photographer can work with the Commonwealth, as needed, to get any confirmations or changes to the state's point-of-contact and then get published.

Possibly, and I emphasize possibly, the author of these technical requirements was trying to assure a minimum of post processing alterations? See bullet point 2 about free of digital alterations. Alas, their language won't achieve a finished image from a qualified photographer, as well as they've created requirements that will tend to exclude all the JPEG-only photographers.

Exactly! I suspect that maybe one of the regular posters of misinformation on this site wrote those regulations. 😜🤪

Superflly. The Nikon D500 at 20.9 MP produces 5868x3712. I agree with your premise though.

Yes there is a lot of nonsense there. all that I am responding to is the post.

I am well aware of the xmp side care but that is not the only way editing info is stored it can also be stored within the file. I use the side care. If they have changed the ability to store the info within the document I haven't heard about it.
After editing in ACR and saving the raw file when reopening and viewing the image all of my edits are there and I can continue editing or undo any or all of my previous edits. So yes I do have an edited raw file thaat can still be edited more or in different ways as I choose.

You said " I need to break it to you:"
No, you have nothing new.

Well, I need to break it to you, Adobe never saves anything to the original raw file. You can either save it in an xmp or you can save it with the data in a DNG file.
