I have an Olympus Pen E-PL5 and when I display my pictures from my SDXC card they appear sharp for about 3 seconds and then soften, When I zoom to full screen they sharpen again but now I only get to see a small section of the picture. What is going on and how do I keep my pictures sharp? I am a newbie to this type of camera, all my previous digitals were point and shoot.

I don't know if this is true on a Windows computer, but I have found that on my Mac viewing at some percentages look soft. 100, 50, and 25% will look sharp. 33% and 67% will look softer.

The computer hardly matters, it is the viewing program that might be doing that, it probably gets confused and interpolates badly when at "odd" display settings..

Like in Windows FastStone Viewer there's the option for smoothing and also treating the view to a sharper option. It looks good no matter what screen % is chosen.

Smooth of course eliminates the stairstep pixels if you wander above 100% view, just makes it look nicer and more like it would print.

When you display them where?

Are you shooting RAW + JPEG?

Are you using LR to look at these?
 
Thank you for responding. I have my E-PL5 camera set to LN for image quality and iAUTO for exposure and AF on. I load the memory card to my laptop and it is Windows10 photo viewer. However, not trusting MS Windows10, I also loaded the pictures to the Olympus Viewer 2 software that came with the camera and I got the same results, just OK JPEGS (not using RAW) and then when using the magnify option I am amazed at the picture sharpness and exposure. Do I need to change some settings, I can't believe I am the first person to have this problem but I cannot find any answers on the internet.
 
The reason that I asked about Lightroom (LR) is that it loads an initial low-res image and then spends a few seconds loading the high res version and applying color curves and what-not to it before displaying it, and the behavior that you're seeing kind of sounded like that.

I don't know the Oly program, so I can't really comment on that.

How do the images look if you open them e.g. in the Windows viewer directly?

It sounds like the image viewing programs may be the problem.

My standard image upload, viewing and simple fiddling program is FastStone Viewer and it is so good that I did make a donation. http://www.faststone.org/FSViewerDetail.htm

One point to understand is that the usual laptop screen is maybe 1920 or maybe 1366 pixels wide, or sometimes smaller like my netbook at 800 wide. The software needs to compress the 4608 pixels wide image to that 1366 (or whatever) pixels wide to display it on the screen thus compressing some fine detail out of existence on the display.

When you display a portion of the image at 100% image pixel to screen pixel relationship then you get to see the actual detail that the camera recorded.

.....................................................add-on.......................................

If you had one of the fancy new Mac high resolution displays or a 4K monitor then you would see something that looks better but there would still be some pixel fiddling to make the 4608 pixels wide fit the whatever pixels wide screen.

You would not see the "real image" until you get a display that has 4608 pixels wide by 3456 pixels high to display it as it is (at 4:3 ratio), and for normal viewing distance it would need to be at least 15 inches wide.

The Photos app in Windows 10 is set by default to automatically enhance your photos. Usually it does not do a good job. You can disable this behaviour in the Photo app's settings.

I haven't used Olympus Viewer 2 but if it is anything like 3 it won't be a great way to view images.

I second the recommendation to try Faststone Image Viewer. It is fast and displays jpegs and raw images in good quality.
 
...... I also loaded the pictures to the Olympus Viewer 2 software that came with the camera and I got the same results......
Best to download Olympus Viewer 3 to get any improvements, but I guess the same issue will be apparent. http://support.olympus-imaging.com/ov3download/ (use '123456789' as a serial number for the download, it works for me, saves reading the camera number).

Oly Viewer 3 is designed to do raw file conversions from Oly raw files only, but it can handle any jpegs from any camera make.

Thank you to all who replied. I downloaded and tried FastStone and Olympus Viewer 3 and obtained the same results as before so I guess its like Guy says, I need a bigger monitor or one that can handle more pixels. I had more luck viewing pictures from my old Fuji F31fd compact at 6 megapixels. It seems like such a waste of camera horsepower to be able to shoot pictures with great detail and sharpness and never be able to appreciate the results. Why have others not complained about this especially the full frame photographers. Surely they have more pixels and resolution than my Pen E-PL5. What do they use to see their JPEGS?
 
Another point is that the resolution of the average monitor is significantly less than that of the average print.

The photo labs usually print at 300 dpi, monitors are variously maybe 75 to 100 pixels per inch, so display at about 3 times or more worse resolution than the print.

Just checking my notebook right now and the screen is 13.5 inches wide and the pixel width is 1366, so that comes to 1366/13.5=101 pixels per inch approx.

So for a full width display every screen pixel is trying to display 4608/1366=3.73 approx pixels. That approx 3.73 to 1 scrunching up naturally loses some degree of apparent resolution.

Even worse is displaying a 4:3 ratio image as then the width on my screen falls to about 10.2 inches, that means the factor is now about nearly a 5:1 scrunching of camera pixels to screen pixels.

Possibly a display 'zoom' issue? Different programs will have different capabilities to render an image at intermediate zoom levels. Depending on your screen resolution, a "fit to window" zoom might end up being something weird, like 28% or 23%. In many of the programs that I use, the best on-screen rendering happens at 100%, 50% or 25%. If I view at, say, 33%, the image looks less sharp on screen.

That still doesn't explain why the image seems to go less sharp after a few seconds, unless the image display is being 'built' with a multi-pass of information.
 
As others have stated, seems like a zoom "issue" or perhaps better put "feature" of image viewing.

If you see a sharper image for a short time, this is most likely because the viewing software first shows a quick-to-process preview with some crude down-sampling algorithm which often results in a sharp looking image, but with jaggies and maybe pixelation. Afterwards you'll see the better down-sampled image, with smoother appearance but which may seem a bit soft to some eyes.

With normal computer screens, this is just a by-product of having to down-size the images quite a lot.
 
Thank you Guy for pointing out the cause of the problem. Let me ask you this, do I need to learn RAW photography and would that help? I know very little about RAW photography and have no experience with it. I never had a camera that was able to take RAW pictures before this one so I would need to read up on it if you think it would be worth my while. Do you have any suggestions or ideas about this or am I straying from a workable solution.

Just as a side note I read your web pages on the E-PL1 and E-PL5 and now I have a much better understanding of some of the camera functions and I thank you for that. Someone at Olympus needs to supplement their documentation department with some real down to earth people like yourself. The manual was clearly produced by engineers and technicians who fully understand all the camera function and don't feel the need to explain how they work, just how to turn them on and adjust them. It is very overwhelming for someone trying to graduate from point and shoots to pro or semi pro cameras.
 
Thank you Guy for pointing out the cause of the problem.
This problem that you see has never been a problem for me in many years of peering at screens, I guess that I must be accepting that the screens I own do not show the "whole picture" in as much as I would need currently a monitor of 4608x3456 pixels that would need to be around about 24 inches screen width minimum and viewed rather closely to see all that the pixels that inhabit those files.

When working on edits of images then usually the whole image is displayed way way smaller anyway due to the real estate required for the edit program with all its sliders and junk. That's why sensible programs use a simple double click on the image to toggle between available window fill and 100% pixel display, or like FastStone when you get full screen display you can press "1" or "2" etc to get 100% or 200% views of some of the image. That is all to do with checking sharpening and noise control adjustments where pixel peeping is of use.
Let me ask you this, do I need to learn RAW photography
Yes.
and would that help?
No.

Still the same display issues if that is your main problem.
I know very little about RAW photography and have no experience with it.
It's about as easy as fiddling with jpegs but better control and adjustment is available as you are dealing with the data from the sensor and not the camera's jpeg version of data which is 8 bit per colour and compressed to varying degrees. More at the end....
I never had a camera that was able to take RAW pictures before this one so I would need to read up on it if you think it would be worth my while. Do you have any suggestions or ideas about this or am I straying from a workable solution.
There is no realistic "solution" to your perceived problem, we all have always worked this way. Most times looking at the whole scrunched image to judge overall brightness, contrast, saturation etc, then a portion at 100% to see the effects of sharpening and noise reduction if needed. A good quality IPS monitor properly calibrated lets us make sensible decisions about adjustments to the image.
Just as a side note I read your web pages on the E-PL1 and E-PL5 and now I have a much better understanding of some of the camera functions and I thank you for that.
All my stuff is just my memory store of things that I mostly found here on the forum. Having found it then it makes sense to make it available to all. It definitely needs a huge rework to make it more user friendly and that has started (slowly) only on my hard drive so far.
Someone at Olympus needs to supplement their documentation department with some real down to earth people like yourself.
No, then people would say that I am just a mouthpiece for the company, and I for one would never let that happen. Witness Robin Wong and his Olympus pages, he now works for Olympus and is definitely not afraid of criticising where due, but still is sometimes called a "fraud" just because Olympus now employs him. The usual idiots here find faults with people if they can't find enough faults with the camera gear.
The manual was clearly produced by engineers and technicians who fully understand all the camera function and don't feel the need to explain how they work, just how to turn them on and adjust them. It is very overwhelming for someone trying to graduate from point and shoots to pro or semi pro cameras.
Yup, I see your pain. The "lesser" cameras often have spectacularly good manuals explaining WHY you need a feature. Olympus can't even manage to tell us all the details of what happens in the cameras let alone WHY you may need to use a feature.

There is absolutely no reason why they can't make a good complete and explanatory PDF manual to be available for download, mainly because the days of supplying printed manuals are long gone and all we do is download anyway.

Picking up on raw file talk......

Now that I am getting better at using raw converters, currently DxO, always buying only during discount periods for original version and then the upgrades. So the software costs need to be considered but can be significantly cheaper when looking for Black Friday sales and the like.

There are of course free converters like Olympus Viewer 3, slow and a bit cumbersome and mostly only providing exactly what the camera itself does as they both share the Apical image processing logic. The main criticism with the camera jpegs and the Oly Viewer 3 output is that some degree of noise reduction and sharpening is applied even though we attempt to reduce that to nothing at times for various reasons. Other raw converters are more controllable.

The initial issue with raw files is the size of storage. No problem now that SD cards and disk drives are so darn cheap, so I always shoot raw+jpeg and keep the lot even though I may at times just use the jpeg for casual shots and sharing in the family.

As I get better (questionable always) with raw conversion then it become much clearer to me that I should have always taken raw+jpeg so now I could go back some years to those raws and do a better job with favourite images. The trick being that raw converters get better and better as the years pass by and manage to make old cameras look better than ever if the raw files were to be available.

Just like I did a city visit some months back and took only my old Panasonic LX3 in a belt pouch. Raw+jpeg of course, but when I applied the raw files to DxO suddenly I was looking at an old camera with renewed respect.

Anyway, often it is not so much about using raw files to do better jpegs than the camera, often it's about using the raw files to do a totally different jpeg compared to what the camera can do.

So, even if you do not want to fiddle with raw files then it is definitely worth facing the storage problem and taking either all raw+jpeg or only doing that for shots judged to be difficult, and maybe some time in the future coming back to wrestle with the raw files.

Of course managing all your files can be a pain, but slowly I found that using FastStone Viewer to upload from cards into auto day dated folders and later add some useful text to that dated folder name, and keep a separate day dated folder structure for the raw files. For me stuff seems easier to find that way.

My folders end up looking something like this......

That trip sadly I took only jpegs, now I wish I had taken raw+jpeg.

Whatever you do the most important thing is to always have backups, all my computers at home have a pocket sized USB drive plugged in where auto backups of all my stuff that is useful happens every 30 minutes or so (SyncBack SE does that and there is a free version). Plus more copies of the backups as well, so maybe the whole image file system exists in up to 5 places at home on various drives and also a big Network Storage device. It has saved me a few times when computers die or some badly done delete goes all wrong.

Guy,

Thank you so much for all of your advice and recommendations, I can't tell you how much I appreciate it. I will look for some good affordable RAW software starting with DxO. I have a learning curve ahead of me but it is something I feel is worthwhile. You have given me a great start with both guidance and direction and I could not ask for more.

Guy,

All the usual raw converters have 30 day free trial periods to see if you like them or not.

Don't worry too much about raw files yet except maybe to shoot raw+jpeg for those shots that may need help with dynamic range, highlight recovery, noise reduction etc. You can always come back later and revisit old raw files as the conversion programs are always improving. Like DxO Elite version has the quite amazing Prime noise reduction as an option. DxO Elite is on discount currently but still expensive at US$149 https://shop.dxo.com/us/photo-software/dxo-opticspro

The fastest raw converter is Corel AfterShot Pro 3, definitely worth a 30 day trial, and is often heavily discounted. It sprang from an old converter called Bibble which was highly regarded in its day. http://www.aftershotpro.com/en/products/aftershot/pro/
You have given me a great start with both guidance and direction and I could not ask for more.
Well, I'm no real authority, just make sure that you read as widely as possible.

A Wiki page gives some free and paid options for raw converters.... https://en.wikipedia.org/wiki/Raw_image_format and there's a lot more than that available.

Regards..... Guy
 
That's it, problem solved, thank you Guy. Went into Faststone viewer and then went to Smooth - it was already checked - guess it is a default - and chose the Lacros sharper option and still no luck, so I went back to the Smooth option and unchecked the box and then displayed my pictures and they all appeared much sharper, just as sharp as when I zoom in. This is the view I have been waiting for.
