Photographing art work

Go to last post
Thanks Mike. I completely agree with you on Photoshop, I've had it years and still only use it for very basic stuff, Paintshop pro is much easier to use.

I have a polarising lens and was looking for something to put over the lights, putting up a sheet as you suggest could do the trick, I guess it's just a case of experimenting.

The main reason for buying the A77 was the poster size photo's it said it could take (in the right hands) It's only my lack of knowledge and experience that's stopped it from doing a decent job. Following all the advice on here I have had far better results over the past few days. I've attached the most recent photo, it has been tinkered with on paintshop pro and the demo version of Neat Image that I'm quite impressed with, it's very close to what I'm looking for, do you think the resolution is as good as I could get with the A77? I've yet to have a go with the HDR function, still got a

Is this the A77 or A77ii? Was it RAW or JPEG? What settings did you use on the camera? What lens and focal length? For some reason all the EXIF information is stripped from the photo.
 
It's the A77 Tom, taken in RAW and jpeg. I think it would have been the RAW version saved in jpeg via the Neat Image demo download as it only allows saves in jpeg. I've took some screen prints of the details The camera dial was set on "A" I had it on a tripod and used the remote release control.

The result looks fine, but it's only 12MP. The A77 can capture up to 24MP. Did you intentionally not want to fill the frame?

There's no reason to use HDR for this job, and I don't know why anyone suggested it. What it does is change the way tones are rendered in scenes where the dynamic range exceeds what the camera can record. It does that by reducing the contrast between the brightest and darkest parts of scenes. I'm sure you don't want that to happen with your paintings, whose dynamic range when viewed under real life conditions is already well within the capabilities of the A77. For the most accurate depiction of the tones, stick with regular shots.

I thought the camera automatically took photo's at 24mp if set on the large image size, is there a way to ensure it does it in future? I didn't fill the whole frame because of slight distortions around the edges (rectified in paintshop pro)

If you've set your camera to large image size it sounds like your shooting in JPEG rather than RAW ?

In which case your letting the camera throw away a lot of the information it would otherwise capture .

You might have said your shooting RAW already and I've missed it .

When you process the RAWs in modern software , you really can get much more out of them .

If your working with JPEGs your only working with what's left after the old software that Sony used in the cameras a long time back .

My first DSLR was the Sony a100 who had terrible high ISO, when ISO 400 was the highest that was useable , 800 was poor and 1600 , it's highest setting , was unusable.

Using more modern software the RAW files are capable of so much more now than what I had in 2007 .

So if your not already , and want the best the camera can give , shoot RAW .

It's normal to expect something less than 24MP if you don't quite fill the frame. The more you crop the excess from the result, the lower the pixel count will be. Just take a shot of anything and make sure the full capture is 6000 x 4000 pixels.

Just took a couple of shots in RAW so it filled the frame and can see what you are saying, checked the dimensions and they are 6000x4000. Don't know what happened with the earlier shots, I assume the camera must have gone to 12mp as a default setting because I wasn't filling the frame fully. Thanks for that info. that's quite a revelation and should make a lot of difference. I will make sure in future I'm getting as much from the camera that I can.
 
I suspect...

Terry,

First of all, great art!

Now then, I suspect that your image was placed as you would normally view it and you used the camera as you might normally expect to use is (in landscape orientation).

I also recall on the Hurricane image that there was white space on either side.

So, if you had your image vertical and your camera horizontal and the art had white space it is possible that you didn't "fill the frame" with the colored portion of the art. Thereby resulting in a smaller image.

When the final image gets converted to jpg, the jpg conversion will make great reductions in those areas of large white.

You don't need to photograph the white since once you send the image to be reproduced they will be able to select the size of reproduction and place your colored art within that with the white space surrounding it.

You might want to try orienting the camera to optimize the capture of the colored portion of your art and doing what you did when you processed Catalina. Then you should probably decide how you're going to have your prints produced and do a trial to see if you're going to get something you like.

...or in raw + jpg which allows you to select the level of jpg used.
 
Terry is processing the raw and then editing with both PSP (which doesn't save the EXIF) and using Neat Image to reduce noise.

So, he is starting with the 24MP raw file and losing megapixels in post.

I'm making some assumptions here based on the image shown here.

That image shows a large white border and a title.

Being hand painted I would have thought it wouldn't have a perfectly straight line at the edge of the painting .

I'm just guessing though, I've no idea what the edges of the original canvas looked like , or how the photos were taken .

I've done paintings on pre-stretched canvas where I didn't paint all the way out to the edge and over the corner.

It's very possible that the posted image of "Hurricane" was trimmed to the color and dropped into a white border and then posted. Terry said it was shot by a friend and it was a pretty large file.

There's been a lot of assumptions made by everyone trying to help Terry.
 
Thank you very much Gary for your comments on the art work, much appreciated, you are the first guys to see it other than family and friends so it's great getting such positive comments beyond that.

The Hurricane photo was taken by a friend who was doing a University course in photography, it was taken in one of their studios, she hadn't done art work before so I think she did a great job, unfortunately for me she had to come out of the course due to having a baby.

The white border and text was put on later but I take your point on orienting the camera to get more of the painting in the frame and less background, I didn't know the MP would reduce with less of the painting in the frame.

I'm confused with Hurricane photo saying it's 151MP, looking at the properties on a another photo she took she used a Canon EOS R , I can't find such a camera on google with that amount of pixels, the highest I've seen for that camera is 50.6MP.

The whole issue of prints is another minefield, there's a printer just round the corner that I can maybe get some advice from, I can show them a few images on a USB stick and see what they can do.

It's quite likely that she took several shots and stitched them later to make sure you had a good file size for printing big .

Four photos with a good overlap would give you 151mp easily .

To get the same size file with your a77 would just need more shots as mentioned earlier .

It just depends how big an image is needed to print at the intended size .
 
Without the white border, the image is about 118MP. It could have been a stitched multi-shot or possibly an upscale?

If you look here , you'll see that Canon had an EOS R and an EOS Ra released in 2018 that had a 30MP sensor.
