Olympus has its own way of showing the resolution settings. It is OK once you get used to it. Turn the Camera On. (On the back you will see an OK button surrounded by 4 arrows.) Press the OK button to bring up the menu. Press the left arrow button That should bring up a choice of: TIFF, SHQ, HQ, SQ1, SQ2 Use the up/down arrow buttons to move the cursor to SQ1 Then press the right arrow button That should bring up a choice of settings. Use the up/down buttons to select a setting. I suggest you select 2048x1536 (which is 3 megapixels) Then press the OK button. ................ You should think about getting a memory card with a greater capacity.
